The last hurdle is audio. Can you tell me how to bring audio into the ADV7842/ADV7511 evaluation board?
1) to digitize anlogue stereo audio (RCA connections and leads to i2s for input to the 7511.
2) to record the analogue audio at up to at least 96khz/24 bit and 192khz/24bit if possible
3) to convert digital optical audio (s/pdif) to I2S for input into the 7511. The source for this will be my laserdisc player which has an optical out connection. This in turn depends on whether I elect to use the laserdiscs analogue or digital audio channels and output connections. These channels are selectable from the laserdisc players remote. I have yet to decide on whether i want to use analogue or digital from my laserdisks.
I have investigated i2s and it looks like there are problems with it on PCB to PCB conncetions. I am interested to hear what you say on this.
I have looked over your ADAU1761 chip - its a DAC as well as an ADC. I am just looking into DACs. Shall look into your ADAU1761 further.
