General Description

The DS4125, DS4150, DS4155, DS4156, DS4160,

DS4250, DS4300, DS4311, DS4312, DS4622, and

DS4776 ceramic surface-mount crystal oscillators are

part of Maxim’s DS4-XO series of crystal oscillators.

These devices offer output frequencies at 125MHz,

155.52MHz, 156.25MHz, 160MHz, 311.04MHz, 312.5MHz,

622.08MHz, and 77.76MHz. The clock oscillators are

suited for systems with tight tolerances because of the

jitter, phase noise, and stability performance. The small

package provides a format made for applications

where PCB space is critical.

These clock oscillators are crystal based and use a fun-

damental crystal with PLL technology to provide the

final output frequencies. Each device is offered with

LVDS or LVPECL output types. The output enable pin is

active-high logic.

These clock oscillators have very low phase jitter and

phase noise. Typical phase jitter is < 0.7ps

RMS

from

12kHz to 20MHz. The devices are designed to operate

with a 3.3V ±5% supply voltage, and are available in a

5.0mm x 3.2mm x 1.49mm, 10-pin LCCC surface-mount

ceramic package.
