The FM quadrature mixer converts the FM RF decoder VCO

formula for HIGH side injection: N = ---------------------------------
- ; formula for LOW side injection: N = ----------------------------------
f ref f ref
where:
N = decimal value of PLL word
fRF = the wanted tuning frequency [Hz]
fIF = the intermediate frequency [Hz] = 225 kHz
fref = the reference frequency [Hz] = 32.768 kHz for the 32.768 kHz crystal; fref = 50 kHz for the 13 MHz crystal or
when externally clocked with 6.5 MHz.

4 × ( 100 ×10 + 225 ×10 )
Example for receiving a channel at 100 MHz with HIGH side injection: N = ------------------------------------------------------------------ = 12234 .

The PLL word becomes 2FCAH.
2. VRF in Fig.5 is replaced by VRF1 + VRF2. The radio is tuned to 98 MHz (HIGH side injection).
3. LOW side and HIGH side selectivity can be switched by changing the mixer from HIGH side to LOW side LO injection.

16 SOLDERING To overcome these problems the double-wave soldering

method was specifically developed.
16.1 Introduction to soldering surface mount
packages If wave soldering is used the following conditions must be
observed for optimal results:

16.3 Wave soldering

Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.

Notes
1. For more detailed information on the BGA packages refer to the “(LF)BGA Application Note” (AN01026); order a copy
from your Philips Semiconductors sales office.
2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.
3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account
be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature
exceeding 217 °C ± 10 °C measured in the atmosphere of the reflow oven. The package body peak temperature
must be kept as low as possible.
4. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder
cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side,
the solder might be deposited on the heatsink surface.
5. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
6. Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is definitely not
suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
7. Wave soldering is suitable for SSOP, TSSOP, VSO and VSSOP packages with a pitch (e) equal to or larger than
0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
8. Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered pre-mounted
on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar
soldering process. The appropriate soldering profile can be provided on request.
9. Hot bar soldering or manual soldering is suitable for PMFP packages.
