PRELIMINARY INFORMATION
The ICS650-11B is a low cost, low jitter, high
performance clock synthesizer customized for
BroadCom. 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 25.0 MHz,
33.33 MHz, 66.66 MHz, 100.0 MHz, and
133.33 MHz. All output clocks are frequency
locked together. The ICS650-11B outputs all
have 0 ppm synthesis error.
