for 61 ns at the frame boundary. The frame pulse, running at a 8 KHz rate,
will be the same format (ST-BUS or GCI-BUS) as the input frame pulse
(FP8i).
Frame Pulse Output (Three-state Output). Frame pulse output is active
for 122 ns at the frame boundary. The frame pulse, running at 8 KHz rate,
will be the same style (ST-BUS or GCI-BUS) as the input frame pulse
(FP8i).
Local Serial Output Streams 0 to 15 (5 V Tolerant Three-state
Outputs). These pins output serial TDM data streams at a data-rate of:
16.384 Mb/s (with 256 channels per stream),
8.192 Mb/s (with 128 channels per stream),
4.096 Mb/s (with 64 channels per stream), or
2.048 Mb/s (with 32 channels per stream).
The data-rate is independently programmable for each output stream.
Refer to descriptions of the LORS and ODE pins for control of the output
High or High-Impedance state.
Local Output Channel High Impedance Control (5 V Tolerant Three-
state Outputs).
Active high output enable: used to control, on a per-channel basis, the
external buffering of Local output streams.
LCSTo0 is the output enable for streams: LSTo[0,2,4,6,8,10,12, and 14].
LCSTo1 is the output enable for streams: LSTo[1,3,5,7,9,11,13, and 15].
Refer to descriptions of the LORS and ODE pins for control of the output
High or High-Impedance state.
Output Drive Enable (5 V Tolerant, Internal pull-up).
An asynchronous input providing Output Enable control to the BSTo0- 31,
LSTo0-15, BCSTo0-3 and LCSTo0-1 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)
and the outputs BCSTo0-3 and LCSTo0-1 are driven low.
When HIGH, the outputs BSTo0- 31, LSTo0-15, BCSTo0-3 and LCSTo0-1
are enabled.
Frame Pulse Output (Three-state Output). Frame pulse output is active
