Local Output Reset State (5 V Tolerant Input with Internal
Pull-down).
When this input is LOW, the device will initialize with the
LSTo0-15 outputs driven high, and the LCSTo0-1 outputs
driven low. Following initialization, the Local 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 LCSTo0-1.
When this input is HIGH, the device will initialize with the
LSTo0-15 outputs at high impedance and the LCSTo0-1
outputs driven low. Following initialization, the Local stream
outputs may be set active or high impedance using the ODE
pin or on a per-channel basis with the LE bit in the Local
Connection Memory.
Local Serial Output Streams 0 to 7 (5 V Tolerant
Three-state Outputs with Slew-Rate Control).
In Local 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 Local 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 LORS and ODE pins for
control of the output HIGH or high impedance state.
