TDA18274

Hybrid (analog and digital) silicon tuner for terrestrial and

cable TV reception
Rev. 1 — 11 February 2013 Product short data sheet

1. General description
The TDA18274 is a high performance silicon tuner designed for terrestrial and cable TV
reception for both analog and digital signals.

The TDA18274 supports all analog and digital TV standards and delivers a Low IF (LIF)
signal to a demodulator for analog TV and/or a channel demodulator for digital TV.

The TDA18274 facilitates TV design by:

• Allowing on-board integration

• Drastically reducing the tuner Bill Of Material (BOM)
• Providing flexibility in system solution development
• Allowing straightforward and cost effective multi-tuner applications optimization

2. Features and benefits

only)
 2 programmable General-Purpose Outputs (GPO)
 1.7 MHz, 6 MHz, 7 MHz, 8 MHz and 10 MHz channel bandwidths
 LIF channel center frequency output ranging from 0.8 MHz to 7.5 MHz
 Fully integrated IF selectivity; eliminating the need for external SAW filters
 Large flexibility in the IF filtering stage to ease the matching with various demodulators
circuits
 Single-ended RF input, no need for external balun
 Up to 1 GHz RF input capability
 Excellent return loss compatible with cable requirements
 Power Level Detector (PLD) embedded
 Integrated gain control
 Self-AGC synchronization mode (VSync) for analog reception

[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. The
junction temperature: Tj = Tamb + Tj-c. where Tj-c = power  Rth.
