My customer is using ADV7842 part and they are following EVAL-ADV7842-7511_rev1p2_schems_20140930 file for schematics reference.
In this SDR SDRAM is connected to ADV7842.Can i replace this with DDR SDRAM directly connect to ADV7842 and without using Blackfin processor.
Can you share any schematics reference where DDR is connected directly to ADV7842.
The schematic is attached .
We are looking in to your question.
The ADV7842 memory is dedicated to the ADV7842 and can not be shared with the Blackfin. The entire Blackfin processor section can be replaced with a processor of your choice.
ADV7842 uses the it's memory only for SDP 3D comb and Frame Based Correction so if you do not require these features, the ADV7842 does not need the external memory.
