We are using ADV7403 for PAL input and we have a delay requirement for this decoding operation. However, in standard defition processor section,
ADV7403 user manual says "DCT[1:0] Digital Clamp Timing" time constant is 100 msec in fast mode[DCT:10] (page 132) which is a very high value for us. Is this time constant process one-time operation at the beginning or do we have to wait 100 msec for every new frame /field? Moreover, when DCT[1:0] is determined by ADV7403 (DCT:11), can "100msec time constant" be improved significantly?
What is the total approximate delay between output and input (in case of using curent clamp also) for a PAL video in this decoder?
