General Description
The MAX3625B is a low-jitter, precision clock generator
optimized for networking applications. The device inte-
grates a crystal oscillator and a phase-locked loop
(PLL) clock multiplier to generate high-frequency clock
outputs for Ethernet, 10G Fibre Channel, and other net-
working applications.
Maxim’s proprietary PLL design features ultra-low jitter
and excellent power-supply noise rejection, minimizing
design risk for network equipment.
The MAX3625B has three LVPECL outputs. Selectable
output dividers and a selectable feedback divider allow
a range of output frequencies.
