VBI data-bus from Video Decoder. Usually used also for delivering
the digital video samples.
VBI clock from Video Decoder. Used to sample the VBI data in
its positive edge. This clock is used for capturing and storing the
VBI data.
This is the ZR36505 Global clock, which comes from the
NT1004.
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.
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.
"Bulk-Fifo full" indication signal from NT1004. This signal is
normally '0', and is set to '1' when the ZR36504Bulk -Fifo is full.
Audio Codec Frame-Sync pulse for Left channel., which comes
from the NT1004. The ZR36505 uses this signal to trigger the
beginning of its VBI Bulk data output immediately after the 16th
