DS4-XO Series Crystal Oscillators
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 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.
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 < 0.6psRMS 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.

Detailed Description
The devices consist of a fundamental-mode, AT-cut
crystal and a synthesizer IC that can synthesize any
one of these frequencies: 77.76MHz, 125MHz,
155.52MHz, 156.25MHz, 160MHz, 311.04MHz,
312.5MHz, and 622.08MHz.
All devices support two types of differential output dri-
vers: LVDS and LVPECL. When the OE signal is low,
LVPECL outputs go to the PECL_BIAS level of
VCC - 2.0V, while the LVDS outputs are a logical one.
See Figures 2 and 3 for an LVDS and LVPECL output
timing diagram.
