Low-Jitter, Precision Clock

Generator with Three Outputs

MX3625A

General Description

Features

The MAX3625A 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.

♦ Crystal Oscillator Interface: 24.8MHz to 27MHz

♦ CMOS Input: Up to 320MHz

♦ Output Frequencies

Ethernet: 62.5MHz, 125MHz, 156.25MHz, 312.5MHz

10G Fibre Channel: 159.375MHz, 318.75MHz

♦ Low Jitter

Maxim’s proprietary PLL design features ultra-low jitter

and excellent power-supply noise rejection, minimizing

design risk for network equipment.

♦ Excellent Power-Supply Noise Rejection

♦ No External Loop Filter Capacitor Required

The MAX3625A has three LVPECL outputs. Selectable

output dividers and a selectable feedback divider allow

a range of output frequencies.
