DS4106/DS4212/DS4425
106.25MHz/212.5MHz/425MHz
Clock Oscillators
Rev 2; 4/08
General Description
The DS4106, DS4212, and DS4425 ceramic surfacemount 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 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 < 0.9ps 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.

ELECTRICAL CHARACTERISTICS
(VCC= 3.0V to 3.6V, TA= -40°C to +85°C, typical values are at VCC= +3.3V and TA= +25°C, unless otherwise noted.) (Note 1)
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.
