Using the Raytheon TMC22153 Video Decoder
Raytheon has a whole family of video parts. Any member of the
family can be used. The user must select the part needed based
on the requirements of the application. Because the Raytheon
part does not include the A/Ds, an external A/D is necessary in
this design (or a pair of A/Ds for S video).
The part can be used in CCIR-656 (D1) mode for a zero con-
trol signal interface. Special attention must be paid to the video
output modes in order to get the right data to the right pins (see
the following diagram).
Note that the circuit in Figure 19 has not been built or tested.

Figure 16. Alternate Stand-Alone Application Design
Using the ADV611/ADV612 In Stand-Alone Applications
Figure 16 shows the ADV611/ADV612 in a noncomputer
based applications. Here, an ADSP-2185 digital signal proces-
sor provides Host control and BW calculation services. Note
that all control and BW operations occur over the host interface
in this design.
Connecting the ADV611/ADV612 to Popular Video Decoders
and Encoders
The following circuits are recommendations only. Analog
Devices has not actually built or tested these circuits.
Using the Philips SAA7111 Video Decoder
The SAA7111 example circuit, which appears in Figure 17, is
used in this configuration on the ADV611 CCTVPIPE demon-
stration board.

Using the Analog Devices ADV7175 Video Encoder
Because the ADV7175 has a CCIR-656 interface, it connects
directly with the ADV611/ADV612 without “glue” logic. Note
that the ADV7175 can only be used at CCIR-601 sampling
rates.
The ADV7175 example circuit, which appears in Figure 18, is
used in this configuration on the ADV611 CCTVPIPE demon-
stration board.
