PCM6240-Q1: Does PCM6240 support daisy -chain output

Fei Jiang

Part Number: PCM6240-Q1

As we can see from the spec, PCM6240 can support TDM daisy chain input. What about daisy chain output(route like figure below)? This can save one TDM port of DSP.

Hi Fei,

Yes, multiple devices can share the same data line as shown. It is supported. Each device should be configured to put the data into different slots.

Hi Brian，

If we use TDM8 for DSP input. the two PCM6240 occupy 4 slots respectively. When one of PCM6240s is outputing data, can the other one switch to high impedence mode seamlessly?
