Frame Pulse Output (5 V Tolerant Three-state Output).
When the Frame Pulse Width bit (FPW) of the Control
Register is LOW (default), this pin outputs a 61 ns-wide frame
pulse. When the FPW bit is HIGH, this pin outputs a
122 ns-wide frame pulse. The frame pulse, running at 8 kHz
rate, will have the same format (ST-BUS or GCI-Bus) as the
input frame pulse (FP8i). Output data on both the Backplane
and Local sides (BSTo0-31 and LSTo0-15) will be aligned to
this frame pulse and the accompanying output clock, C16o.
Backplane Serial Input Streams 0 to 15 (5 V Tolerant
Inputs with Internal Pull-downs).
In Backplane Non-32 Mbps Mode, these pins accept 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 input
stream.
In Backplane 32 Mbps Mode, these pins accept serial TDM
data streams at a fixed data rate of 32.768 Mbps (with 512
channels per stream).
Backplane Serial Input Streams 16 to 31 (5 V Tolerant
Inputs with Internal Pull-downs).
In Backplane Non-32 Mbps Mode, these pins accept 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 input
stream.
In Backplane 32 Mbps Mode, these pins are unused and
should be externally connected to a defined logic level.
