Product details

52.5 MHz LVPECL MEMS oscillator for high-speed clock trees

Supply voltage spans 2.25V to 3.63V, covering both 2.5V and 3.3V logic rails without an extra regulator. The standby function (Power Down) drops supply current to 5 µA max, useful for power-gated subsystems in battery-powered or energy-conscious designs.

Microchip lists the DSC1202NE1-52M50000T as Active. The 6-VDFN package (7.00mm x 5.00mm, 0.90mm seated height) is a standard surface-mount footprint with a low profile suitable for dense PCB layouts.

Commercial temperature grade — indoor and office environments

The ±50 ppm frequency stability is typical for a basic XO; if the application requires tighter holdover over temperature, a TCXO or OCXO variant would be needed.

Frequently asked questions

What is the difference between the DSC1202 and DSC1203 series?

The DSC1202 series (this part) outputs LVPECL, while the DSC1203 series outputs LVDS. Both are MEMS-based XOs with the same package and supply range. Choose LVPECL for higher voltage swing and DC-coupled termination; choose LVDS for lower power and AC-coupled links.

Can I use a standard quartz crystal oscillator instead of this MEMS oscillator for 52.5 MHz?

A quartz crystal oscillator at 52.5 MHz is possible, but the MEMS resonator in the DSC1202 offers better shock and vibration immunity, faster startup, and a smaller footprint. If your design already uses a quartz oscillator with the same 6-VDFN footprint and LVPECL output, it may be a drop-in replacement — verify the supply voltage range and frequency stability (±50 ppm) against your quartz oscillator's specs.
