ICS650R-07T集成电路（IC）的时钟发生器PLL频率合成器规格书PDF中文资料

描述 Description

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.
