EST0
Expansion Bus Serial data stream 0 (Three-state output/input)
. This is a bi-
directional pin at 8.192 Mb/s in IDX Link mode. In TDM Link mode this is a 2.048,
4.096 or 8.192 Mb/s output stream.

EST1
Expansion Bus Serial data stream 1 (Three-state output/input)
. This is a bi-
directional pin at 8.192 Mb/s in IDX Link mode. In TDM Link mode this is a 2.048,
4.096 or 8.192 Mb/s input stream.

ODE
Output Device Enable (Input)
. This is the output enable input for the serial
outputs. If this input is low, STo0, STo1, EST0, EST1 are high impedance. If this
input is high, each channel may still be put into high impedance state by using per
channel control bit in the Connection Memory.

C8
Clock 8.192 (Bidirectional)
. As an input this signal is used for Expansion bus
and/or internal clock source at 8.192 MHz depending on the timing mode
selected. As an output this signal is an 8.192 MHz output clock locked to the
reference input signal.
45
4
F8
Frame Pulse for 8.192 MHz (Bidirectional)
. As an input accepts and
automatically identifies frame synchronization signals formatted according to ST-
BUS and GCI interface specifications. As an output is an 8 KHz frame pulse that
indicates the start of the active frame. Either F8 or FPi are used for frame
synchronization depending on the timing mode selected

C8P_C16i
Oscillator Master Clock (CMOS Input)
. For crystal operation, a 8.192MHz
crystal is connected to this pin from OSCo. For clock oscillator operation, this pin
is connected to a clock source. The clock source of either 8.192 MHz or 16.384
MHz can be used as selected in the Timing Control Register (TC).

OSCo
Oscillator Master Clock (CMOS Output)
. For crystal operation, a 8.192MHz
crystal is connected from this pin to C8P_C16i. For clock oscillator operation, this
pin is left unconnected.

FPi
Frame Pulse (Input).
This input accepts and automatically identifies frame
synchronization signals formatted according to ST-BUS and GCI interface
specifications. Either F8 or FPi are used for frame synchronization depending on
the timing mode selected.
