control of the output HIGH or high impedance state.
Backplane Output Channel high impedance Control (5 V
Tolerant, Three-state Outputs). These pins control external
buffering individually for a set of Backplane output streams on
a per-channel basis.
When LOW, the external output buffer will be tri-stated.
When HIGH, the external output buffer will be enabled.
In Backplane Non-32 Mbps Mode (stream rates 2 Mbps to
16Mbps):
BCSTo0 is the output enable for BSTo0,4,8,12,16,20,24,28
BCSTo1 is the output enable for BSTo1,5,9,13,17,21,25,29
BCSTo2 is the output enable for BSTo2,6,10,14,18,22,26,30
BCSTo3 is the output enable for BSTo3,7,11,15,19,23,27,31.
In Backplane 32Mbps Mode (stream rate 32Mbps):
BCSTo0 is the output enable for BSTo0,4,8,12
BCSTo1 is the output enable for BSTo1,5,9,13
BCSTo2 is the output enable for BSTo2,6,10,14
BCSTo3 is the output enable for BSTo3,7,11,15.
Refer to the descriptions of the BORS and ODE pins for
control of the output LOW or active state.
Backplane Serial Output Streams 16 to 31 (5 V Tolerant,
Three-state Outputs with Slew-Rate Control).
In Backplane Non-32 Mbps Mode, these pins output serial
TDM data streams at a data rate of:
16.384 Mbps (with 256 channels per stream),
8.192 Mbps (with 128 channels per stream),
4.096 Mbps (with 64 channels per stream) or
2.048 Mbps (with 32 channels per stream).
The data rate is independently programmable for each output
stream.
These pins are unused when the Backplane 32 Mbps Mode is
selected. Therefore, the value output on these pins during
Backplane 32 Mbps Mode (either driven-HIGH or high
impedance) is dependent on the configuration of the BORS
pin.
