WM8595

Production Data

PD, Rev 4.2, January 2011

I2S MODE

In I2S mode, the MSB of input data is sampled on the second rising edge of bit clock following a

left/right clock transition. The MSB of output data changes on the first falling edge of bit clock

following a left/right clock transition, and may be sampled on the next rising edge of bit clock.

Left/right clocks are low during the left channel audio data samples and high during the right channel

audio data samples.

LEFT JUSTIFIED (LJ) MODE

In LJ mode, the MSB of the input data is sampled by the WM8595 on the first rising edge of bit clock

following a left/right clock transition. The MSB of output data changes on the same falling edge of bit

clock as left/right clock and may be sampled on the next rising edge of bit clock. Left/right clock is

high during the left channel audio data samples and low during the right channel audio data

samples.
