General Description

The DS4625 is a dual-output, low-jitter clock oscillator
capable of producing frequency output pair combina-
tions ranging from 100MHz to 625MHz. The device
combines an AT-cut crystal, an oscillator, and a low-
noise phase-locked loop (PLL) in a 5.0mm x 3.2mm
surface-mount LCCC package. Standard frequency
options are listed in the

Ordering Information/Selector

Guide

table. For custom frequency options, contact the

.

The DS4625 provides dual, low-voltage, positive emit-
ter-coupled logic (LVPECL) clock output drivers. The
output drivers can be enabled and disabled through
the OE pin, which is an active-high CMOS input that
has an internal pullup resistor. When high, both output
pairs are enabled.

The device operates from a single +3.3V ±10% supply.
The operating temperature range is -40°C to +70°C.
