DS4250P+

P1-P3P4-P6P7-P8
General Description
The DS4125, DS4150, DS4155, DS4156, DS4160,
DS4250, DS4300, DS4311, DS4312, DS4622, and
DS4776 ceramic surface-mount crystal oscillators are
part of Maxim’s DS4-XO series of crystal oscillators.
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 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 < 0.7ps
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.
