HIGH LEVEL COMMAND INTERFACE
The I2C-bus interface is used to pass control commands and data between the SAA5264/SAA5265 and the television
microcontroller. The interface uses high-level commands, which are backward compatible with the SAFARI.

EMC GUIDELINES
Optimization of circuit return paths and minimization of
commonmode emission will be assisted byusinga double
sided Printed Circuit Board (PCB) with low inductance
ground plane.
On a single-sided PCB a local ground plane under the
whole IC should be presentas shown in Fig.3. This should
have the widest possible connection between the PCB
ground and bulk electrolytic decoupling capacitor.
Preferably, the PCB local ground plane connection should
not be connected to other grounds on route to the PCB
ground. Do not use wire links. Wire links cause ground
inductance which increases ground bounce.
The supply pins can be decoupled at the ground pin plane
below the IC. This is easily achieved by using surface
mount capacitors, which, at high frequency, are more
effective than components with leads.
Using a device socket would increase the area and
therefore increase the inductance of the external bypass
loop.
To provide a high-impedance to any high frequency
signals on the VDD supplies to the IC, a ferrite bead or
inductor can be connected in series with the supply line
close to the decoupling capacitor. To prevent signal
radiation, pull-up resistors of signal outputs should not be
connected to the VDD supply on the IC side of the ferrite
bead or inductor.
OSCGND should only be connected to the crystal load
capacitors and not to any other ground connection.
Distances to physical connections of associated active
devices should be as short as possible.
PCB output tracks should have close proximity, mutually
coupled, ground return paths.

SOLDERING
Introduction to soldering through-hole mount
packages
This text gives a brief insight to wave, dip and manual
soldering.Amore in-depth account of soldering ICs can be
found in our
Packages”
Wave soldering is the preferred method for mounting of
through-hole mount IC packages on a printed-circuit
board.
Soldering by dipping or by solder wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joints for more than 5 seconds.
Suitability of through-hole mount IC packages for dipping and wave soldering methods
DBS, DIP, HDIP, SDIP, SILsuitablesuitable
Note
1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either below the seating plane or not more than
2 mm above it. If the temperature of the soldering iron bit
is less than 300 °C it may remain in contact for up to
10 seconds. If the bit temperature is between
300 and 400 °C, contact may be up to 5 seconds.
