PRELIMINARY INFORMATION
The ICS650-14B is a low cost, low jitter, high
performance clock synthesizer customized for
networking systems applications. Using analog
Phase-Locked Loop (PLL) techniques, the device
accepts a 25.0 MHz clock or fundamental mode
crystal input to produce multiple output clocks of
one fixed 25.0 MHz, a four (plus one) frequency
selectable bank, and two frequency selectable
clocks. All output clocks are frequency locked
together. The ICS650R-14B outputs
all have 0 ppm synthesis error.
