MCLK
Master Clock input. This 4.096 MHz clock is used as an internal master clock and must be
provided during both ST-BUS and SSI modes of operation. This is a TTL level input.
In ST-BUS mode the MCLK input (also known as C4i in ST-BUS terms) is derived from the
synchronous 4.096 MHz clock available from the layer 1 transceiver device. The C4i
clock,
input to MCLK, is used in this mode as both the internal master clock and for deriving the
C2o output clock and EN1/EN2 output enable strobes.
In SSI mode a 4.096 MHz master clock must be derived from an external source. This
master clock may be asynchronous relative to the 8 kHz frame reference.

F0i
Frame alignment input pulse for ST-BUS interface operation. This input should be tied low
if ST-BUS operation is not required.
This is a TTL level input.

C2o
2.048MHz Clock output for ST-BUS applications. This clock is MCLK divided by 2 and
inverted. The C2o output activity state is governed by the F0i input pin condition.
