Clock Board The Clock Board provides the following resources shared

by the digital channels of a 128 pins module:

The Master Clock Generator generates the system’s

master clock. The master clock is the timing reference for

all timings. The master clock pulse is generated by the

clock board that has been configured as master (usually

the clock board of the 128 pins module 1). The master

clock signal is distributed to all 128 pins modules as the

timing reference of the system.

The voltages generated by the Reference Voltage Gener-

ator are used for DC calibration.

The High-Precision PMU is used for high-precision DC

measurements (refer to “High-Precision PMU” on

page 47).

The clock board is connected to the Control Board, which

provides a data/decompression circuit for vector data and

makes the fiber optic connection to the workstation.

For technical details and descriptions of all components

and their modes of operation, refer to the SOC Series

Service Guide.
