Hello All!
I am about to begin a design where a stable 48kHz signal should be generated from a PAL video sync signal.
PAL offers several extractable frequencies chipsets as 50Hz, 15.625kHz,...
The 48kHz should be used as a reference signal for AES/EBU audio.
Are there chips(ets) that can generate 48kHz or 96kHz from a PAL input? If not there should be some combination of dplls that can manage those frequency relationship.
We are having an FPGA on our board. We could also use the FPGA to build an ADPLL for thsi purpose. Can this be then exact enough for studio Audio equipment?
Thanks for any suggestion that lead me into the right direction.
