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.


  • 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
