Ground.
Ground Rail.
VCC +5.0 Volt Power Supply.
Data Acknowledgment O This active LOW output indicates that a data bus transfer is complete. A pull-up resistor is required at this
(Open Drain)
output.
RX Input 0 to 7
I Serial data input streams. These streams have 32 channels at data rates of 2.048 Mb/s.
Frame Pulse
I This input accepts and automatically identifies frame synchronization signals formatted according to different
backplane specifications such as ST-BUS® and GCI.
Clock
I 4.096 MHz serial clock for shifting data in and out of the data streams.
Address 0 to 5
I These lines provide the address to IDT728985 internal registers.
Data Strobe
I This is the input for the active HIGH data strobe on the microprocessor interface. This input operates with
CS to enable the internal read and write generation.
Read/Write
I This input controls the direction of the data bus lines (D0-D7) during a microprocessor access.
Chip Select
I Active LOW input enabling a microprocessor read or write of control register or internal memories.
Data Bus 0 to 7
I/O These pins provide microprocessor access to data in the internal control register. Connection Memory HIGH,
Connection Memory LOW and data memory.
TX Outputs 0 to 7
(Three-state Outputs)
O Serial data output streams. These streams are composed of 32, 64 Kbit/s channels at data rates of 2.048 Mb/s.
Output Drive Enable
I This is an output enable for the TX0-7 serial outputs. If this input is LOW, TX0-7 are high-impedance. If this is
HIGH, each channel may still be put into high-impedance by software control.
Control Channel Output O This output is a 2.048 Mb/s line which contains 256 bits per frame. The level of each bit is controlled by the
contents of the CCO bit in the Connection Memory HIGH locations.
