PCM and I2C Interfaces

EG95 provides one Pulse Code Modulation (PCM) digital interface for audio design, which supports the
following modes and one I2C interface:



Primary mode (short frame synchronization, works as both master and slave)



Auxiliary mode (long frame synchronization, works as master only)

In primary mode, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising
edge.  The  PCM_SYNC  falling  edge  represents  the  MSB.  In  this  mode,  the  PCM  interface  supports
256kHz,  512kHz,  1024kHz  or  2048kHz  PCM_CLK  at  8kHz  PCM_SYNC,  and  also  supports  4096kHz
PCM_CLK at 16kHz PCM_SYNC.

In auxiliary mode, the data is also sampled on the falling edge of the PCM_CLK and transmitted on the
rising edge. The PCM_SYNC rising edge represents the MSB. In this mode, the PCM interface operates
with a 256kHz, 512kHz, 1024kHz or 2048kHz PCM_CLK and an 8kHz, 50% duty cycle PCM_SYNC.

EG95  supports  16-bit  linear  data  format.  The  following  figures  show  the  primary  mode’s  timing
relationship  with  8KHz  PCM_SYNC  and  2048KHz  PCM_CLK,  as  well  as  the  auxiliary  mode’s  timing
relationship with 8KHz PCM_SYNC and 256KHz PCM_CLK.
