I/O Type
Description
O
3.3 V, PCM Output Clocks.
4 mA
These outputs are used to drive the PCM data/CAS out to the
E1 or DS1 lines.
In Structured CES mode, ST-BUS format SToCLK is 4.096
MHz; Generic format SToCLK is 1.544 MHz or 2.048 MHz for
DS1; or 2.048 MHz for E1.
In Unstructured CES mode, these pins provide 1.544 MHz for
DS1 or 2.048 MHz for E1.
O
3.3 V, Output Frame Pulses.
4 mA
In Structured CES mode, these pins are output frame pulses
which set the frame boundaries for the outgoing data and
CAS. These signals are programmable as either multiframe
pulses or frame pulses.
Not used in Unstructured CES mode.
O
3.3 V, Serial PCM Data Outputs.
4 mA
In Unstructured CES mode, each pin carries a 1.544 Mbps or
2.048 Mbps serial stream.
In Structured CES mode, each pin carries a 1.544 Mbps or
2.048 Mbps serial stream which contains a 24-channel data
stream in DS1 operation or a 32-channel data stream in E1
operation.
O
3.3 V, Serial PCM Signalling Outputs or Output Loss of Signal
4 mA
(LOS) Indicators.
In Structured CES mode, these pins output CAS signalling.
In Unstructured CES mode, each of these pins outputs an
LOS or general purpose signal based on a user-programma-
ble value in TDM Control Register 3 for the corresponding
port.
