ADSP-214xx SHARC Processor Hardware Reference 14-1
14 PRECISION CLOCK
GENERATOR
The precision clock generators (PCG) consist of four units, each of which
generates a pair of signals (clock and frame sync) derived from a clock
input signal. The units, A B, C, and D, are identical in functionality and
operate independently of each other. The two signals generated by each
unit are normally used as a serial bit clock/frame sync pair. Table 14-1
lists the PCG specifications.
