I have a working ADAU1701 solution using Analog Inputs but need to add an external SPDIF with SRC @ 48k output to the design.
Setup as follows and attached jpegs:
1) ADAU1701 as Slave to external 256fs MCLK.
2) Data, BITCLK, and LRCLK connected to MP1-Input Sdata-1, MP4-Input LRCLK, MP5-Input BCLK and MCLKI
3) SCH Input Block 1,2,4 & 5 Active
4) Programable MUX Nx2-1
Note: when using Analog input and SPDIF Not Locked signal throughput is good.
Note: when SPDIF locks and all data and clks present at ADAU1701, MUX switched to I2S input 4&5, result is NO signal throughput.
What am I missing???
Are there any eval applications available with I2S functioning?
What is the 1701 expecting for BIT Clk rate 64fs?
Is I2S 24Bit input OK?
