MAX3673ETN+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

General Description

The MAX3673 is a low-jitter frequency synthesizer that accepts two reference clock inputs and generates nine phase-aligned outputs. The device features 40kHz jitter transfer bandwidth, 0.3psRMS (12kHz to 20MHz) integrated phase jitter, and best-in-class power-supply noise rejection (PSNR), making it ideal for jitter cleanup, frequency translation, and clock distribution in wireless base-station applications.
