Description

The MAX3627 is a low-jitter, precision clock generator optimized for network applications. The device integrates a crystal oscillator and a phase-locked loop (PLL) to generate high-frequency clock outputs for Ethernet applications.

Maxim's proprietary PLL design features ultra-low jitter (0.4psRMS) and excellent power-supply noise rejection (PSNR), minimizing design risk for network equipment.

The MAX3627 contains seven LVDS outputs and one LVCMOS output. The output frequencies are selectable among 125MHz, 156.25MHz, and 312.5MHz.
