Zarlink Semiconductor Inc.
Read/Write (5 V Tolerant Input): This input controls the
direction
microprocessor access.
Data Strobe (5 V Tolerant Input): This active low input works
in conjunction with CS to enable the microprocessor port read
and write operations.
Address 0 - 11 (5 V Tolerant Inputs): These pins form the 12-
bit address bus to the internal memories and registers.
Serial Input Streams 0 to 15 (5 V Tolerant Inputs): The data
rate of these input streams can be selected independently
using the stream input control registers. In the 2.048 Mb/s
mode, these pins accept serial TDM data streams at
2.048 Mb/s with 32 channels per stream. In the 4.096 Mb/s
mode, these pins accept serial TDM data streams at
4.096 Mb/s with 64 channels per stream. In the 8.192 Mb/s
mode, these pins accept serial TDM data streams at
8.192 Mb/s with 128 channels per stream.
Unused serial input pins are required to connect to either Vdd
or ground, through an external pull-up resistors or external pull-
down resistor.
Device Reset (5 V Tolerant Input): This input (active LOW)
puts the device in its reset state that disables the STo0 - 15
drivers and drives the STOHZ 0 - 15 outputs to high. It also
clears the device registers and internal counters. To ensure
proper reset action, the reset pin must be low for longer than
1 ms. Upon releasing the reset signal to the device, the first
microprocessor access can take place after 600 µs due to the
time required to stabilize the APLL block from the power down
state.
Test Serial Data Out (3 V Tolerant Three-state Output):
JTAG serial data is output on this pin on the falling edge of
TCK. This pin is held in high impedance state when JTAG is not
enabled.
No Connection Pins. These pins are not connected to the
device internally.
