K2
DS Data Strobe (5V Tolerant Input): This active low input works in
conjunction with CS to enable the read and write operations.
L2
R/W Read/Write (5V Tolerant Input): This input controls the direction of
the data bus lines (D0-D15) during a microprocessor access.
L1
CS Chip Select (5V Tolerant Input): Active low input used by a
microprocessor to activate the microprocessor port.

M6, N5, N6, M7,
D0 - 7, Data Bus 0 -15 (5V Tolerant I/O): These pins form the 16-bit data bus
D8 - D15 of the microprocessor port.
N7
DTA Data Transfer Acknowledgment (5V Tolerant Three-state Output):
This active low output indicates that a data bus transfer is complete. A
pull-up resistor is required to hold a HIGH level when the pin is tri-
stated.
N8, M8, N9,
N10
STi0 - 3
Serial Input Streams 0 to 3 (5V Tolerant Inputs): In 2Mb/s or
Subrate Switching mode, these inputs accept data rates of 2.048 Mb/s
with 32 channels per stream. In 8Mb/s mode, these inputs accept data
rates of 8.192 Mb/s with 128 channels per stream.
M9, N11, L9, STi4 - 11 Serial Input Streams 4 to 11 (5V Tolerant Inputs): In 2Mb/s or Sub-

input accepts data rate of 2.048Mb/s with 32 channels per stream
respectively. In Sub-rate Switching mode, this pin accepts 2.048Mb/s
with 128 channels per stream for Sub-rate switching application.
M12, M13, L12 STi13 - 15 Serial Input Streams 13 to 15 (5V Tolerant Inputs): In 2Mb/s mode,
these inputs accept a data rate of 2.048Mb/s with 32 channels per
stream.
L13
ODE Output Drive Enable (5V Tolerant Input): This is the output enable
control for the STo0 to STo15 serial outputs and STio0 to STio31 serial
bidirectional outputs.
K13, K12, J13,

these outputs have data rates of 8.192 Mb/s with 128 channels per
stream
H11, H13, H12, STo4 - 7, Serial Output Streams 4 to 11 (5V Tolerant Three-state Outputs): In
G13, G12, F13, STo8 - 11 2Mb/s or Sub-rate Switching mode, these outputs have data rates of
F12, E13
2.048Mb/s with 32 channels per stream
E12
STo12 Serial Output Streams 12 (5V Tolerant Three-state Output): In 2Mb/
s mode, this output has data rate of 2.048Mb/s with 32 channels per
stream. In Sub-rate Switching mode, this pin has data rate of 2.048Mb/
s with 128 channels per stream for Sub-rate switching application.
D13, E11, C13 STo13 - 15 Serial Output Streams 13 to 15 (5V Tolerant Three-state Outputs):
