My custromer has a product using the PCM2912 and their new possible end customer needs custom information put into the descriptor fields. Is this possible? The d/s references this capability, but we need to know min qty, etc. any info about that?
regards, G Biner, Arrow LA
Please contact your local TI Sales Office for more details about this.
Keep in mind some other devices can modify descriptors via EEPROM: PCM2704/5/6/7 is a good place to look.
Hello, thanks for response. The customer needs a codec function, not just DAC, so the PCM27xx won't work. The PCM29xx doesn't seem to have this descriptor modify feature. Can you suggest a codec like this? Thx, G Biner
Hmmm, I don't think we have a solution for this... i can't even think of a cheesy way to do this.
OK, here, maximum cheese. Use the TAS1020B (yeah, it's NRND...) and put your codec on the I2S pins on it. the TAS1020B reads the descriptor out of the EEPROM.

Thanks, Don, that's pretty much what I thought. I'll advise them of that, although it is a bigger and costlier solution. G Biner
