MAXIM DS4125, DS4155, DS4156, DS4160, DS4311 Technical data

General Description

The DS4125, DS4155, DS4156, DS4160, DS4311,
DS4312, DS4622, and DS4776 ceramic surface-mount
crystal oscillators are part of Maxim’s DS4-XO series
crystal oscillators family. 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 fun­damental 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 < 0.6ps

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.

ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VCC= 3.135V to 3.465V, TA= -40°C to +85°C, unless otherwise noted.)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
