Product details

MEMS oscillator at 103.125 MHz — what it replaces

The DSC1122CI2-103.1250T is a MEMS-based XO, not a quartz crystal oscillator. Output is LVPECL, a differential signal that requires 50-ohm to VCC-2V termination at the receiver.

Temperature range and supply tolerance

The ±25ppm frequency stability holds across that band — no external temperature compensation needed. Supply voltage spans 2.25V to 3.6V, so it runs from a 3.3V or 2.5V rail without a separate regulator.

Product status is Active per Microchip.

Frequently asked questions

What are the operating temperature limits for DSC1122CI2-103.1250T?

This is the industrial temperature grade — suitable for outdoor, automotive cabin, and factory-floor environments. The ±25ppm frequency stability is specified across this entire range.
