NETWORKING CLOCK SYNTHESIZER
DATASHEET
ICS650-11
Description
The ICS650-11 is a low cost, low jitter, high performance
clock synthesizer customized for BroadCom. Using analog
Phase-Locked Loop (PLL) techniques, the device accepts a
25.0MHz clock or fundamental mode crystal input to
produce multiple output clocks of 25.0MHz, 33.33MHz,
66.66MHz, 100.0MHz, and 133.33MHz. All output clocks
are frequency locked together. The ICS650-11 outputs all
have 0 ppm synthesis error.
Features
Packaged in 20-pin narrow SSOP, Pb-free
25.00 MHz fundamental crystal or clock input
Five fixed output clocks of 25.0 MHz, 33.33MHz,
66.66MHz, 100.0MHz, and 133.33MHz
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
