SI5328集成電路（IC）的應(yīng)用特定時鐘/定時規(guī)格書PDF中文資料

Description

The Si5328 is a jitter-attenuating precision clock multiplier for Synchronous Ethernet applications requiring sub 1 ps jitter performance and ultra-low loop bandwidth. Whencombined with a low-wander, low jitter reference oscillator, the Si5328 meets all of the wander, MTIE, TDEV, and other requirements listed in ITU-T G.8262/Y.1362. The Si5328 accepts two input clocks ranging from 8 kHz to 710 MHz and generates two output clocks ranging from 8 kHz to 808 MHz. The two outputs are divided down separately from a common source.
