DS4212AN+

P1-P3P4-P6P7-P8
DS4106/DS4212/DS4425
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.
