PCM1808: -I2S BCLK/LRCLK Counts - Similar ADC families

Adam Kiss

Part Number: PCM1808
Other Parts Discussed in Thread: PCM1801, TLV320ADC3120, PCM1804

Dear Sir or Madam,

I have an only I2S Master capable device driving a PCM1808PWR ADC in slave mode.

Turns out that the masters output is a 32BCLK/LRCLK setup, which the datasheet of the PCM1808 states it is unsupported.
I have contacted the manufacturer of the Master device to see if the protocol setup can be changed there, but I was wondering if there is a similar/replacement device from your product lineup which supports 32BCLK/RLCLK operation?

Kind regards,

Adam

Hello Adam,

Would either PCM1801 or TLV320ADC3120 be options for you?

Hi Carson,

The first one seems like a good option. The TLV320ADC3120 only has 1 single ended input. I would need two of those to be able to swap in the new IC without extensive modifications. PCM1804 I have used in other applications before, and if i get the datasheet right, the 1801 is the same family, only with hardware control instead of I2C.
The only problem at the moment is stock. I cannot seem to get them in any reliable quantity within the next 3 months.
