Detailed Description
The DS4625 is a dual-output, low-jitter clock oscillator
that produces frequency output pair combinations as
shown in the
Ordering Information/Selector Guide table.
The phase relationship between the outputs is not guar-
anteed. The device combines an AT-cut, fundamental-
mode crystal, an oscillator, and a low-noise PLL in a
5.0mm x 3.2mm surface-mount LCCC package.
The DS4625 provides dual LVPECL clock output dri-
vers. The output drivers can be enabled and disabled
through the OE pin. The OE pin is an active-high CMOS
input that has an internal pullup resistor. When OE is
high, both output pairs are enabled.
