PIN DESCRIPTIONS
SYMBOL
NAME
I/O
DESCRIPTION
GND
Ground.
Ground Rail.
VCC
VCC
+3.3 Volt Power Supply.
DTA
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.
RX0-7
RX Input 0 to 7
I
Serial data input streams. These streams have 32 channels at data rates of 2.048 Mb/s.
F0i
Frame Pulse
I
This input identifies frame synchronization signals formatted to ST-BUS® specifications.
C4i
Clock
I
4.096 MHz serial clock for shifting data in and out of the data streams.
A0-A5
Address 0 to 5
I
These lines provide the address to IDT72V8980 internal registers.
DS
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.
R/
W
Read/Write
I
This input controls the direction of the data bus lines (D0-D7) during a microprocessor access.
CS
Chip Select
I
Active LOW input enabling a microprocessor read or write of control register or internal memories.
D0-D7
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.
TX0-7
TX Outputs 0 to 7
O
Serial data output streams. These streams are composed of 32, 64 Kbit/s channels at data rates of 2.048 Mb/s.
ODE
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.
CCO
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.
RESET
Device Reset
I
This input (active LOW) puts the IDT72V8980 in its reset state that clears the device internal counters,
(Schmitt Trigger Input)
registers and brings TX0-7 and microport data outputs to a high-impedance state. The time constant for a
power up reset circuit must be a minimum of five times the rise time of the power supply. In normal operation,
the
RESET pin must be held LOW for a minimum of 100ns to reset the device.
