Product details

Quad-output MEMS oscillator replaces four cans

The DSC400-2222Q0022KE2T is a MEMS-based XO (Standard) from Microchip that packs four LVPECL outputs into a single 5.00 mm x 3.20 mm package — replacing up to four discrete crystal oscillators on the BOM. Outputs are configured as 125 MHz, 100 MHz, 100 MHz, and 125 MHz, covering the two most common reference frequencies for 1GbE MAC/PHY pairs and PCIe root complexes.

Lifecycle and supply: active, no EOL watch

Supply voltage and enable logic

Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails without an external regulator.

Frequently asked questions

What is the output type and frequency of the DSC400-2222Q0022KE2T?

LVPECL outputs, four channels: 125 MHz, 100 MHz, 100 MHz, and 125 MHz.

Is there a pin-compatible alternative to the DSC400-2222Q0022KE2T in the DSC400 family?

The DSC400 series includes multiple frequency-configuration variants in the same 20-VFQFN package. A different order code with the same base number (DSC400) and matching supply voltage, output type, and stability will share the same footprint — but the output frequency plan will differ. Check the Microchip ordering guide for the exact frequency set you need.
