Product details

MEMS XO with four programmable outputs

The DSC400-4244Q0069KE1T is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering four independent clock outputs: two at 100 MHz and two at 161.1328125 MHz. Outputs are HCSL or LVPECL compatible, and the device includes an Enable/Disable function for power management. The MEMS resonator eliminates quartz crystal startup issues and offers better shock/vibration immunity in industrial environments.

Supply voltage spans 2.25V to 3.6V, so it runs on 2.5V or 3.3V rails without a separate regulator.

Package dimensions and footprint

Housed in a 20-VFQFN with exposed pad, the body measures 5.00mm x 3.20mm x 0.90mm.

Frequently asked questions

Is DSC400-4244Q0069KE1T compatible with a 2.5V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so a 2.5V rail is within spec. The device also runs on 3.3V without any configuration change.

What is the exact footprint and package dimensions for DSC400-4244Q0069KE1T?

Package is 20-VFQFN with exposed pad, body size 5.00mm x 3.20mm, height 0.90mm. The exposed pad requires a thermal via array in the PCB layout.
