Backplane Output Reset State (5 V Tolerant Input with
Internal Pull-down).
When this input is LOW, the device will initialize with the
BSTo0-31 outputs driven high, and the BCSTo0-3 outputs
driven low. Following initialization, the Backplane stream
outputs are always active and a high impedance state, if
required on a per-channel basis, may be implemented with
external buffers controlled by outputs BCSTo0-3.
When this input is HIGH, the device will initialize with the
BSTo0-31 outputs at high impedance and the BCSTo0-3
outputs driven low. Following initialization, the Backplane
stream outputs may be set active or high impedance using the
ODE pin or on a per-channel basis with the BE bit in the
Backplane Connection Memory.
Backplane Serial Output Streams 0 to 15 (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.
In Backplane 32 Mbps Mode, these pins output serial TDM
data streams at a fixed data rate of 32.768 Mbps (with 512
channels per stream).
Refer to the descriptions of the BORS and ODE pins for
control of the output HIGH or high impedance state.
