Product details

50 MHz LVPECL MEMS oscillator — active, production-ready

Supply range and enable/disable function

The wide supply range of 2.25V to 3.6V lets this oscillator run off a 2.5V or 3.3V rail without an extra LDO — a single capacitor on the Vdd pin is enough when the supply is clean.

Housed in a 6-SMD no-lead package measuring 0.098" × 0.079" (2.50 mm × 2.00 mm) with a seated height of 0.035" (0.90 mm), this oscillator fits into the compact footprint that dense PCB layouts demand. Surface-mount reflow follows standard JEDEC profiles; no special handling beyond the usual ESD precautions.

Frequently asked questions

What is the frequency and output type of the DSC1122DI2-050.0000T?

The oscillator outputs a 50 MHz LVPECL differential clock signal. LVPECL is the standard for driving 50-ohm terminated transmission lines; the DC bias at the output pins is typically Vdd - 1.3V, so AC-coupling is required when interfacing to CML or HCSL inputs.
