I/O DESCRIPTION
Digital 3.3V power supply
Digital ground connection
I Video Vertical-Sync input signal from Video Deco der
I Video Vertical-Sync input signal from Video Decoder
I VBI data-bus from Video Decoder. Usually used also for delivering
the digital video samples.
I 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.
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.
I "Bulk-Fifo full" indication signal from NT1004. This signal is
normally '0', and is set to '1' when the ZR36504Bulk -Fifo is full.
I 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
