3.3V Dual-Output LVPECL Clock Oscillator

The DS4625 is a dual-output, low-jitter clock oscillator capable of producing frequency output pair combinations 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 in the full data sheet. For custom frequency options, contact the factory at:

var domain = "maximintegrated.com";

document.write ("" + name + domain + "");

.

The DS4625 provides dual, low-voltage, positive emitter-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 +85°C.
