I This is the ZR36505 Global clock, which comes from the
NT1004.
O VBI Data Output pin, goes to DAT_IN pin of the
ZR36504(which is used for both Audio CODEC T x chan and
Bulk Data in This pin is Open Drain, and is set to high -z upon
Power-On or Soft Reset. It requires an external pull-up resistor.
O Bulk Data Enable output. When set to '1', Bulk output data at
DAT_OUT pin is sampled into the ZR36504by falling edge of
BCLK .
This pin is set to Hi-Z upon Power -On or Soft Reset.
