In ADV7604 recommendation document there mentions for "TMDS PLL Gear Selection Optimization" , can you please provide some information for what is this used for and when it needs to be implemented?
Basically this helps set up the internal TMDS data capture PLL. Let me ask the expert and see what they recommend.
Is any update for this question?
Not yet, checking again
I've discussed this with our designers.
First off, it's an infinite loop as you pointed out but this is because we recommend that the Video PLL is continuously monitored on ADV7604/14 to determine if the part is locked to the incoming video standard.
This workaround optimizes the PLL configuration. When the PLL is not locked, it is optimized to assist in locking to any incoming video format. When the PLL is locked, it is optimized to assist in maintaining lock to the incoming video format.
It's clear now, thanks a million.
