I/O
I PCM data input.
O PCM Data Out. Eight channels. Serial audio samples relative to DA_BCK and DA_LRCK.
O PCM Left Clock. Identifies the channel for each sample. The polarity is programmable.
– 3.3-V supply voltage for I/O signals.
– Ground for core logic and I/O signals.
Audio External Frequency Clock input or output. DA_BCK and DA_LRCK are derived from
I/O
this clock. DA_XCK can be 384 or 256 times the sampling frequency.
PCM Bit Clock. Divided by 8 from DA_XCK. DA_BCK can be either 48 or 32 times the
O
sampling frequency.
O PCM data out in IEC-958 format or compressed data out in IEC-1937 format.
