NETWORKING SYSTEM CLOCK
Description
The ICS650-14 is a low-cost, low-jitter, high-performance
clock synthesizer customized for networking systems
applications. Using analog/digital Phase-Locked Loop (PLL)
techniques, the device accepts a 25 MHz clock or
fundamental mode crystal input to produce multiple output
clocks of one fixed 25 MHz, a four (plus one) frequency
selectable bank, and two frequency selectable clocks. All
output clocks are frequency locked together. All of the
ICS650-14 outputs have zero ppm synthesis error.
