Hi,
I am working on a video decoder project. To ensure decoder clock synchronization with encoder clock , we are doing clock correction by changing register 0X18 and 0X19 of LMH1983 based on PCR value (program clock reference ) from the encoded stream.
our observation is that the clock jitter goes too high momentarily when we reduce the lmh1983 clock frequency (reduce the 0x19 register values), surprising fact is that the jitter behavior is same even when we keep the register 0X18 constant (msb 2 bits) and only reduce the 0x19 register value by 1.
Is there any way to avoid this condition by setting any of the other configuration registers. keeping in mind that we have to use lmh1983 always in freerun mode. only control allowed is through reg0x18 and 0x19 and these register values are changed once in a minute or two.
Expecting earliest response since we are already behind our schedule.
Regards,
Arjun
