Status
All versions are Not Recommended for New Designs. See Ordering Information for recommended replacements.
Description
The MAX3625 is a low-jitter precision clock generator optimized for networking applications. The device integrates a crystal oscillator and a phase-locked loop
(PLL) clock multiplier to generate high-frequency clock outputs for Ethernet, 10G Fibre Channel, and other networking applications.
Maxim's proprietary PLL design features ultra-low jitter and excellent power-supply noise rejection, minimizing design risk for network equipment.
The MAX3625 has three LVPECL outputs. Selectable output dividers and a selectable feedback divider allow a range of output frequencies.
