PRELIMINARY INFORMATION
ICS650-11B
BroadCom Networking Clock Synthesizer
Description
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.
Features
• Packaged in 20 pin narrow SSOP (Pb free available)
• 25.00 MHz fundamental crystal or clock input
• Five fixed output clocks of 25.0 MHz, 33.33 MHz,
66.66 MHz, 100.0 MHz, and 133.33 MHz
• Zero ppm synthesis error in all clocks
• Ideal for BroadCom BCM5600/BCM5400 chipset
• Full CMOS output swing
• Advanced, low power, sub-micron CMOS process
• 3.0V to 5.5V operating voltage
• Industrial temperature range
