Data Sheet
Clock 4.096 MHz (Output).
This output is used for ST-BUS operation at 2.048 Mbps or
4.096 Mbps.
Clock 8.192 MHz (Output).
This output is used for ST-BUS and GCI operation at
8.192 Mbps.

Clock 2.048 MHz (Output).
This output is used for standard E1 interface timing.
This clock output pad includes a Schmitt input which serves as a PLL feedback path;
proper transmission-line termination should be applied to maintain reflections below
Schmitt trigger levels.
