106.25MHz/212.5MHz/425MHz

Clock Oscillators

Rev 2; 4/08

General Description

The DS4106, DS4212, and DS4425 ceramic surface-

mount crystal oscillators are part of Maxim’s DS4-XO

series of crystal oscillators. These devices offer output

frequencies at 106.25MHz, 212.5MHz, and 425MHz.

The clock oscillators are suited for systems with tight tol-

erances 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 < 0.9ps RMS from

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

with a 3.3V ±10% supply voltage, and are available in a

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

ceramic package.
