... 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 requires a minimum number of external components for proper operation. Decoupling capacitors of 0.01µF should be connected between each VDD and GND on Pins 4 and 6, and Pins 16 and 14, as close to the ICS650-11B as possible. A series termination resistor of 33 output. The 25.00 MHz crystal must be connected as close to the chip as possible. The crystal should be a fundamental mode (do not use third overtone), parallel resonant ...
