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 LSTo0-31) 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)
These pins accept 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).
Backplane Serial Input Streams 16 to 31 (5 V Tolerant Inputs with
Internal Pull-downs)
These pins accept 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 should be externally connected to a defined logic
level.
Local Serial Input Streams 0 to 15 (5 V Tolerant Inputs with
Internal Pull-downs)
These pins accept 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).
Local Serial Input Streams 16 to 31 (5 V Tolerant Inputs with
Internal Pull-downs)
These pins accept 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 should be externally connected to a defined logic
level.
