+3.3 Volt Power Supply.
+5.0 V/+3.3 V Power Supply. If 5 V power supply is tied to these pins,
BSTio0-31 pins will meet 5 V PCI requirements. If 3.3 V power supply is tied
to these pins, BSTio0-31 pins will meet 3.3 V PCI requirements.
Ground.
+3.3 Volt Analog PLL Power Supply. No special filtering is required for this
pin.
Analog PLL Ground
Device Reset (5 V Tolerant Input). This input (active low) puts the device in
its reset state; this state clears the device’s internal counters and registers.
To ensure proper reset action, the reset pin must be low for longer than
400 ns. To ensure proper operation, a delay of 100 µs must be applied
before the first microprocessor access is performed after the RESET pin is
set high. The device reset also tristates LSTo0-15 and BSTio0-31. When in a
RESET condition, the C8_A_io, FRAME_A_io, C8_B_io, and FRAME_B_io
signals are tri-stated.
Backplane Serial Input/Output Streams 0 - 15 (5 V Tolerant PCI I/Os). In
H.110 mode, these pins accept or output (selectable on a per channel basis)
serial TDM data streams at 8.192 Mbps with 128 channels per stream. In the
16 Mbps mode, these pins accept serial TDM data streams at 16.384 Mbps
with 256 channels per stream respectively.
Backplane Serial Input/Output Streams 16 - 31 (5 V Tolerant PCI I/Os).
In H.110 mode, these pins accept or output (selectable on a per channel
basis) serial TDM data streams at 8.192 Mbps with 128 channels per
stream. In the 16 Mbps mode, these pins are tristated internally and should
be connected to ground.
Local Serial Input Streams 0 to 3 (5 V Tolerant Inputs): In 2 Mb/s, 4 Mb/s
or 8 Mb/s mode, these inputs accept data rates of 2.048 Mb/s, 4.096 Mb/s or
8.192 Mb/s with 32, 64 or 128 channels per stream respectively.
Local Serial Input Streams 4 to 7 (5 V Tolerant Inputs): In 2 Mb/s, 4 Mb/s
or 8 Mb/s mode, these inputs accept data rates of 2.048 Mb/s, 4.096 Mb/s or
8.192 Mb/s with 32, 64 or 128 channels per stream respectively.
