3.3V Dual-Output LVPECL Clock Oscillator
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
factory at: [email protected].
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.

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.
