Product details

80.1574 MHz MEMS XO with LVDS and tight stability

Microchip's DSC1123DI5-080.1574T is a MEMS-based XO (Standard) delivering a 80.1574 MHz LVDS output with ±10 ppm frequency stability — the MEMS resonator eliminates quartz start-up and vibration sensitivity, making this a fit for telecom line cards, industrial Ethernet, and FPGA reference clocks where a crystal would need a separate oscillator IC.

Runs on a 2.25V to 3.63V supply, so it can share a 2.5V or 3.3V rail without an extra LDO.

This is a production part, not a last-time-buy or surplus item.

Frequently asked questions

What is the exact frequency stability of DSC1123DI5-080.1574T?

That stability is specified without the aging drift of a quartz crystal — the MEMS resonator holds its frequency tighter over time.
