Ground Rail.
+5.0 Volt Power Supply.
This active LOW output indicates that a data bus transfer is complete. A pull-up resistor is required at this
output.
Serial data input streams. These streams have 32 channels at data rates of 2.048 Mb/s.
This input identifies frame synchronization signals formatted to ST-BUS
specifications.
4.096 MHz serial clock for shifting data in and out of the data streams.
These lines provide the address to IDT728981 internal registers.
This is the input for the active HIGH data strobe on the mcroprocessor interface. This input operates with
CS
to enable the internal read and write generation.
This input controls the direction of the data bus lines (D0-D7) during a mcroprocessor access.
Active LOW input enabling a mcroprocessor read or write of control register or internal memories.
These pins provide mcroprocessor access to data in the internal control register. Connection Memory HIGH,
Connection Memory LOW and data memory.
Serial data output streams. These streams are composed of 32, 64 Kbit/s channels at data rates of 2.048 Mb/s.

This is an output enable for the TX0-3 serial outputs. If this input is LOW, TX0-3 are high-impedance. If this is
HIGH, each channel may still be put into high-impedance by software control.
