8. Functional description
The Silicon Tuner is based on single down-conversion and LIF architecture that allows full
integration of band-pass selectivity and eliminates the need for external SAW filters.

The RF input signal is fed to the Low Noise Amplifier (LNA). Then the signal is applied to
an alignment free RF tuned filter to protect the rest of the tuner function against strong
unwanted signals.

The LIF concept needs complex signals that highly suppress the N + 1 image channel
thanks to image rejection calibration. A complex filter and a IF filter perform the IF
selectivity. The IF filter depends on IF frequency choice and channel bandwidth. The IF

NXP Semiconductors TDA18273HN
Hybrid Silicon Tuner for terrestrial and cable TV reception

filter is built with a IF Low-Pass Filter (LPF), a IF notch filter and a programmable IF
High-Pass Filter (HPF) for more flexibility on IF frequency selection. The IF notch filter
when activated, suppress the residual adjacent N − 1 sound carrier.

Continuous gain control is performed after the RF filters and the IF selectivity. Stepped
AGC is available at all stages (LNA, RF filter, mixer and IF LPF) in order to optimize the
tuner signal-to-noise ratio. Internal broadband level detectors control gain settings of all
stepped AGC and the RF AGC amplifier. The steps in the different stages are
automatically compensated in IF with AGCK to keep a constant IF output level. The
demodulator controls the gain of the IF AGC amplifier to take advantage of the full ADC
dynamic range.

A single LC-VCO operating in the range from 6 GHz to 7 GHz is used within a FRAC-N
phase lock-loop to generate the LO frequency. A crystal oscillator differential input
provides the clock reference signal. Demodulators can use this signal through the crystal
output buffer.

All the programming is performed via I2C-bus transceiver. An embedded test tone
generator is used for automatic calibration at Power-On-Reset (POR).

The power level indicator is used to indicate the RF input signal strengths of the received
channel.

8.1 RF filter
The RF filter block is an alignment free tunable Band-Pass Filter (BPF). At power-up, a
self-calibration is performed which compensates for the external and internal components
frequency spread. The center frequency is automatically tuned to the frequency set using
the I2C-bus to suppress any unwanted interference across the broadband spectrum.

8.2 Crystal output mode

Pins XTOUT1 and XTOUT2 provide a symmetrical sine waveform which drives the
channel demodulator and/or IF demodulator. The load on these outputs must be identical
to ensure optimum performance matching. If only one crystal output is used, the unused
output must be loaded with the same capacitance value. The XTOUT output level can be
set to either 400 mV (p-p) or 800 mV (p-p) single ended, refer Table 32 “Pin AS_XTSEL
decoding”.

8.3 AGC description

The tuner gain is composed of different variable gain stages spread according to the block
diagram (see Figure 1 “Block diagram”). Using the different detectors at different stages,
the gain is distributed to offer best trade-off between linearity and noise. Continuity gain
variation is made in 3 dB steps. The AGCK stage compensates the 3 dB steps to ensure
gain linearity.

The tuner gain is externally controlled via IFAGC voltage level applied to pin VIFAGC. The
RF gain is set automatically, based on the defined AGCn_TOP values.

The different stages gain values are then a combination of the following input parameters:

• Input signal
• TOP values set via I2C-bus

NXP Semiconductors TDA18273HN
Hybrid Silicon Tuner for terrestrial and cable TV reception

• IFAGC voltage level

The programmable Take Over Points (TOP) provide the optimal noise versus linearity
trade-off during reception. The TOP values are carefully selected so that they do not
overload the following stages or have too weak signal-to-noise ratio. They correspond to
thresholds where the gain distribution changes inside the tuner.

In order to avoid instability of gain chain while working around thresholds, a hysteresis is
implemented to avoid gain toggling. This is the reason why there are different values for
TOP-up and/or TOP-down. Its main purpose is to make sure gain switch occurs to prevent
signal distortion along the gain chain.

Fast AGC mode is integrated in the IC to speed up the variable gain convergence. The
Fast AGC mode is set at channel change, for a large input level step and can be
programmed via I2C-bus for search mode.

8.4 Harmonic 3 and harmonic 5 filter (H3H5) and wireless network filter
In addition to the RF tuned filters, a H3H5 filter is implemented to prevent broadband
down-conversion with third and fifth LO harmonics for off-air reception in case of presence
of strong interferer.

NXP Semiconductors TDA18273HN
Hybrid Silicon Tuner for terrestrial and cable TV reception

In addition to the H3H5 filter, extra wireless network filter is implemented also to prevent
broadband down-conversion with 1.7 GHz, 1.8 GHz and 2.4 GHz interferers. The filter is
set automatically depending on RF input frequency.

8.5 Low-pass filter (LPF)

The programmable LPF avoids aliasing of demodulators Analog-to-Digital converters. In
addition, it suppresses the remaining signals. The programming enables signal bandwidth
of 1.7 MHz, 6 MHz, 7 MHz, 8 MHz and 10 MHz.

8.6 High-pass filter (HPF)

The HPF contributes to residual adjacent (N + 1) channel suppression after image
rejection removal. It is intended mainly for digital reception.

8.7 Notch filter

This block is implemented in the IF filters to optionally provide additional robustness
against adjacent analog channels. It reduces the adjacent channel sound carrier level to
prevent overloading of IF output stage. The notch frequency is tracked with LPF settings.

8.8 Self AGC synchronization mode (VSYNC)

A vertical synchronization signal detector is implemented in the IC for negative and
positive modulation. The signal is used for synchronization of stepped AGC amplifiers in
case of analog TV. When the external VSYNC mode is selected (see Table 28), the
external VSYNC signal available at VSYNC pin bypasses the internal generated VSYNC
signal. When the internal VSYNC signal is detected, the synchronization is fully
integrated.

th hold time pulse shaper:

VSYNC signal provided to the tuner allows tuner gain changes only during vertical
synchronization to prevent picture quality degradation during analog reception.

A specific pulse shaper function is available to reshape the signal inside the tuner. The
VSYNC signal duration must be according to Table 5.

If the pulse shaper is enabled, as long as th exceeds 0.2 μs, the pulse shaper reshapes
the VSYNC signal. Should the signal at VSYNC pin be maintained longer than th max
(100 μs) in Table 5, it would lead to unwanted tuner gain changes that could be visible on
the picture during analog reception.

8.10 IR mixer
The LIF concept needs complex signals that highly suppress the N + 1 image channel
thanks to image rejection calibration.

8.11 LO generation
A single LC-VCO operating in the range from 6 GHz to 7 GHz is used within a FRAC-N
phase lock-loop to generate the LO frequency. A crystal oscillator differential input
provides the clock reference signal. This signal is provided to demodulators through the
crystal output buffer.

8.12 Temperature sensor

The temperature sensor can be used to indicate the junction temperature of the IC via
I2C-bus for soldering check. Refer to Section 9.1.2 for detailed description and operation.

8.13 Power level detector

The power level detector indicates the RF input signal strengths of the received channel
via I2C-bus. Refer to Section 9.1.4 for detailed description and operation. The available
strength, in a range from 0 dBμV to 127 dBμV, refers to RMS value for digital TV signals
channels, RMS value of unmodulated signal during synchronization level of the envelope
signal for negative modulated analog TV signals or RMS value of unmodulated signal
during black level of the envelope signal for positive modulated analog TV signals.

12. Limiting values

Table 34. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
Symbol Parameter Conditions Min Max Unit
VCC supply voltage −0.3 +3.6 V
VI input voltage VCC < 3.3 V −0.3 VCC + 0.3 V
VCC > 3.3 V −0.3 +3.6 V
Tstg storage temperature −40 +150 °C
Tj junction temperature - 120 °C
Tamb ambient temperature −20 [1] °C
VESD electrostatic discharge voltage EIA/JESD22-A114 (HBM) −2 +2 kV
EIA/JESD22-C101-C (FCDM) class III[2] 750 - V

[1] The maximum allowed ambient temperature Tamb(max) depends on the assembly conditions of the package and especially on the design
of the Printed-Circuit Board (PCB) and die connection. The application mounting must be done in such a way that the maximum junction
temperature is never exceeded. The junction temperature can be obtained by reading the temperature sensor bit via I2C-bus as
explained in Section 9.1.2 “Temperature sensor”. The junction temperature: Tj = Tamb + ΔTj-c. where ΔTj-c = power × Rth.
[2] Class III: 500 V to 1000 V

[1] Measured in free air as defined by JEDEC standard.

[2] These values are given for information only. The thermal resistance depends strongly on the nature and design of the PCB used in the
application. The thermal resistance given corresponds to the value that can be measured on a multilayer PCB (4 layers) as defined by
JEDEC standard.
[3] The junction temperature influences strongly the reliability of an IC. The PCB used in the application contributes in a large part to the
overall thermal characteristic. It must therefore be ensured that the junction temperature of the IC never exceeds Tj(max) = 125 °C at the
maximum ambient temperature.

17. Soldering of SMD packages

This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.

17.1 Introduction to soldering

Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.

17.2 Wave and reflow soldering

Wave soldering is a joining technology in which the joints are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:

• Through-hole components
• Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.

The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.

Key characteristics in both wave and reflow soldering are:

• Board specifications, including the board finish, solder masks and vias
• Package footprints, including solder thieves and orientation
• The moisture sensitivity level of the packages
• Package placement
• Inspection and repair
• Lead-free soldering versus SnPb soldering

17.3 Wave soldering

Key characteristics in wave soldering are:

• Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
• Solder bath specifications, including temperature and impurities

Hybrid Silicon Tuner for terrestrial and cable TV reception

17.4 Reflow soldering

Key characteristics in reflow soldering are:

• Lead-free versus SnPb soldering; note that a lead-free reflow process usually leads to
higher minimum peak temperatures (see Figure 18) than a SnPb process, thus
reducing the process window
• Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
• Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enough for the solder to make reliable solder joints (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in accordance with
Table 40 and 41

Table 40. SnPb eutectic process (from J-STD-020C)

Package thickness (mm) Package reflow temperature (°C)
Volume (mm3)
< 350 ≥ 350
< 2.5 235 220
≥ 2.5 220 220

Table 41. Lead-free process (from J-STD-020C)

Package thickness (mm) Package reflow temperature (°C)
Volume (mm3)
< 350 350 to 2000 > 2000
< 1.6 260 260 260
1.6 to 2.5 260 250 245
> 2.5 250 245 245

Moisture sensitivity precautions, as indicated on the packing, must be respected at all

times.

Studies have shown that small packages reach higher temperatures during reflow
soldering, see Figure 18.
