comb filter and component video input
SAA7118

INPUT/OUTPUT INTERFACES AND PORTS
The SAA7118 has 5 different I/O interfaces:
Analog video input interface, for analog CVBS and/or
Y and C input signals and/or component video signals
Audio clock port
Digital real-time signal port (RT port)
Digital video expansion port (X-port), for unscaled digital
video input and output
Digital image port (I-port) for scaled video data output
and programming
Digital host port (H-port) for extension of the image port
or expansion port from 8 to 16-bit.
9.1
Analog terminals
The SAA7118 has 16 analog inputs AI41 to AI44,
AI31 to AI34, AI21 to AI24 and AI11 to AI14 for composite
video CVBS or S-video Y/C signal pairs or component
video input signals RGB plus separate sync (or Y-P
B
-P
R
plus separate sync).
Component signals with e.g. sync-on-Y or sync-on-green
are also supported; they are fed to two ADC channels, one
for the video contents, the other for sync conversion.
Additionally, there are four differential reference inputs,
which must be connected to ground via a capacitor
equivalent to the decoupling capacitors at the 16 inputs.
There are no peripheral components required other than
these decoupling capacitors and 18
/56
termination
resistors, one set per connected input signal (see also
application example in Fig.47). Four anti-alias filters are
integrated.
Clamp and gain control for the four ADCs are also
integrated. An analog video output (pin AOUT) is provided
for testing purposes.
