Product details

Active production — no BOM lifecycle risk

The DSC6122CI2A-00AT: This means the BOM line can be committed for production builds without an obsolescence clock.

Dual-frequency output — one oscillator, two clock domains

This XO delivers both 25 MHz and 50 MHz from a single MEMS resonator, selected via the device's internal configuration. A single 4-VDFN package replaces two discrete oscillators, saving board space and reducing procurement line items.

MEMS resonator — shock tolerance and fast startup

The 3.2 mm x 2.5 mm footprint fits dense PCB layouts.

Frequently asked questions

How can I order the DSC6122CI2A-00AT or check current availability?

The DSC6122CI2A-00AT is an active Microchip Technology part.

What does the ±25 ppm frequency stability mean for my design?

For a 50 MHz output, this translates to a maximum frequency error of ±1250 Hz — tight enough for most MCU and FPGA clock inputs without external trimming.
