GS9024 Data Sheet
6. Applications Information
The Typical Application Circuit shown on page 14 is useful for both SMPTE and
DVB-ASI signals. The two AGC capacitors shown however increase the AGC time
constant from the original times shown in earlier SMPTE-only application circuits.
In this case a minimum off-time of 50ms is needed when break-before-make
switching is used at the input in order for the AGC voltage to recover.
