Low-Jitter, Precision Clock Generator

with Two Outputs

MAX362

General Description

Features

The MAX3622 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 and other networking applications.

♦ Crystal Oscillator Interface: 25MHz Typical

♦ Output Frequencies: 125MHz and 156.25MHz

♦ Low Jitter

(1.875MHz to 20MHz)

(12kHz to 20MHz)

RMS

Maxim’s proprietary PLL design features ultra-low jitter

(0.36ps

) and excellent power-supply noise rejec-

♦ Excellent Power-Supply Noise Rejection

♦ No External Loop Filter Capacitor Required

tion, minimizing design risk for network equipment.

The MAX3622 has one LVPECL output and one

LVCMOS output. It is available in a 16-pin TSSOP pack-

age and operates over the 0°C to +70°C temperature

range.
