DS4-XO Series Crystal Oscillators
50312/DS476
General Description
Features
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 fre-
quencies 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 toler-
ances because of the jitter, phase noise, and stability
performance. The small package provides a format
made for applications where PCB space is critical.

♦ LVDS or LVPECL Output Types
♦ 3.3V Operating Voltage
♦ 5.0mm x 3.2mm x 1.49mm, 10-Pin LCCC Ceramic

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 < 0.6ps
from
RMS
12kHz to 20MHz. The devices are designed to operate
with a 3.3V 5ꢀ supply voltage, and are available in a
5.0mm x 3.2mm x 1.49mm, 10-pin LCCC surface-mount
ceramic package.
