Product details

What this quad-output MEMS oscillator does on your board

The DSC400-1133Q0079KE1 is a MEMS-based XO (Standard) oscillator that delivers four independent clock outputs from a single 20-VFQFN package: 100 MHz, 100 MHz, 66.666 MHz, and 25 MHz. Outputs are selectable between LVCMOS and LVDS levels, letting you drive both single-ended logic and differential pairs from the same device without a translator.

Supply rails and temperature range for your BOM

Operating from 2.25 V to 3.6 V, it spans the common 2.5 V and 3.3 V logic rails without an extra regulator — check your rail tolerance; the wide range covers most FPGA and SoC banks.

Housed in a 20-VFQFN with exposed pad, measuring 5.00 mm x 3.20 mm and 0.90 mm tall — the thermal pad needs a via array under it for proper soldering and heat sinking.

Frequently asked questions

Is the DSC400-1133Q0079KE1 compatible with a 3.3 V supply?

Yes, 3.3 V is within the 2.25 V–3.6 V range, so no level shifting is needed.

What is the footprint of the DSC400-1133Q0079KE1?

The 20-VFQFN package measures 5.00 mm x 3.20 mm with a 0.90 mm height. The exposed pad requires a thermal via array for proper solder reflow.

Is the DSC400-1133Q0079KE1 obsolete or end-of-life?

No — Microchip lists it as Active. No EOL notice has been issued, so it remains available for new designs.
