2) Feeding PCM data and clocks from an external source

The following set-up allows the MCLK, BICK, LRCK and SDATA to be fed from an external source to the

AK4358. The AKD4358-B gives you two choices of ports to input these clocks and data. Use PORT3 if you want

to input separate data for SDTI1, SDTI2, SDTI3, and SDTI4. Use PORT4 if you want to input only one data

stream and select which AK4358 data input pins you send data to. You can select this by JP10, JP11, JP12, and

JP13. Shorting these jumpers will send data to that individual SDTI pin and open will leave a pull down resister

connected to that SDTI pin.

3) Feeding 1bit data and clocks from an external source

The following set-up allows 1bit data to be fed to DCLK (pin#22), DSDL1,2,3,4(pin#25,27,29,23), and

DSDR1,2,3,4(pin#26,28,30,24) pins from an external source. This is achieved by feeding these signals to

PORT5(DSD_port). Make sure JP4(DAC_MCLK) is set to EXT, while the other PCM clock jumpers are left

open.
