The ICS650-07B is a low cost, low jitter, high performance clock synthesizer customized for Broadcom. Using analog Phase-Locked Loop (PLL) techniques, the device accepts a 25.00 MHz clock or fundamental mode crystal input to produce multiple output clocks of 25.0 MHz, two 125.0 MHz, 133.33 MHz, and a selectable 33.3/66.6 MHz clock. All output clocks are frequency locked together. The ICS650-07B outputs all have 0 ppm synthesis error.
Do not use the 125 MHz outputs to drive Gigabit Ethernet SERDES. Instead, the 25 MHz clock can be driven into our ICS601 in the X5 mode. The ICS601 has low enough jitter and phase noise for all popular SERDES.
