INPUT/OUTPUT INTERFACES AND PORTS
The SAA7114 has 5 different I/O interfaces:
Analog video input interface, for analog CVBS and/or
Y and C input 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 SAA7114 has 6 analog inputs AI21 to AI24, AI11 and
AI12 for composite video CVBS or S-video Y/C signal
pairs. Additionally, there are two differential reference
inputs, which must be connected to ground via a capacitor
equivalent to the decoupling capacitors at the 6 inputs.
There are no peripheral components required other than
these decoupling capacitors and 18
/56
termination
resistors, one set per connected input signal; see
application example in Fig.41. Two anti-alias filters are
integrated, and self adjusting via the clock frequency.
Clamp and gain control for the two ADCs are also
integrated. An analog video output (pin AOUT) is provided
for testing purposes.
