Hi Team,
I have customer that has one new application requirement for before-market automotive infotainment, as below block, some summary as below items.
Could you help double check if PCM1864 is suitable ?
1) 2 or more I2S or TDM format, digital input interface
2) at lease one Analog input for Mic
3) Mic input gain adjustable, up to 30dB
4) The output is TDM format, connecting to SOC. And it should be able to combine and mix the several input channel into one output.
Some questions that need your help about PCM1864 :
1. Could the DMIN and DMIN2 be used as the I2S or TDM input ?
2. Could the input format set to I2S, while output setting as TDM, or the input also has to be TDM format ? And how to configure ?
3. If it's suitable, PCM1864 should be set in slave mode ? with BCK and LRCLK from SOC, and SCKI could be omitted, or connect from crystal ?
4. Any other more suitable solution for this application requirement ? Like TLC320AIC3268 ?
Thanks for your help in advance.
