Using the ADV601LC In Standalone Applications

Figure 14 shows the ADV601LC in a noncomputer based appli-

cations. Here, an ADSP-21csp01 digital signal processor pro-

vides Host control and BW calculation services. Note that all

control and BW operations occur over the host interface in this

design.

Connecting the ADV601LC 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 15, is

used in this configuration on the ADV601LC Video Lab dem-

onstration board.

Using the Analog Devices ADV7175 Video Encoder

Because the ADV7175 has a CCIR-656 interface, it connects

directly with the ADV601LC without “glue” logic. Note that

the ADV7175 can only be used at CCIR-601 sampling rates.

The ADV7175 example circuit, which appears in Figure 16, is

used in this configuration on the ADV601LC Video Lab dem-

onstration board.

Using the Raytheon TMC22173 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 17 has not been built or tested.
