Output Drive Enable (5 V Tolerant Input with Internal Pull-up)
An asynchronous input providing Output Enable control to the
BSTo0-31 and LSTo0-31 outputs.
When LOW, the BSTo0-31 and LSTo0-31 outputs are driven
HIGH or high impedance (dependent on the BORS and LORS
pin settings respectively).
When HIGH, the outputs BSTo0-31 and LSTo0-31 are
enabled.
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. Following initialization, the
Backplane stream outputs are always active.
When this input is HIGH, the device will initialize with the
BSTo0-31 outputs at high impedance. 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)
These pins output serial TDM data streams at a data rate of:
16.384 Mbps (with 256 channels per stream), or 8.192 Mbps
(with 128 channels per stream).
Refer to the descriptions of the BORS and ODE pins for
control of the output HIGH or high impedance state.
Backplane Serial Output Streams 16 to 31 (5 V Tolerant,
Three-state Outputs with Slew-Rate Control)
These pins output serial TDM data streams at a data rate of:
8.192 Mbps (with 128 channels per stream).
When the device operates at 16.384 Mbps, these pins are
unused, and therefore, the value output on these pins (either
driven-HIGH or high impedance) is dependent on the
configuration of the BORS pin.
Refer to the descriptions of the BORS and ODE pins for
control of the output HIGH or high impedance state.
