Product details

MEMS quad-output clock source for multi-rail timing

The DSC400-3333Q0094KE1 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering four independent LVDS clock outputs from a single resonator: 125 MHz, 100 MHz, 100 MHz, and 50 MHz.

Supply and temperature envelope for indoor gear

Runs on a 2.25 V to 3.6 V supply rail, so it sits comfortably on either a 2.5 V or 3.3 V power domain without a separate LDO. It is not rated for the -40°C floor of industrial or automotive environments.

Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm body, 0.90 mm height), the package requires a thermal pad on the PCB for heat sinking — the exposed paddle must be soldered to a ground plane pour to keep junction temperatures in check.

Frequently asked questions

How can I order DSC400-3333Q0094KE1 or check availability?

The DSC400-3333Q0094KE1 is an active Microchip part. Submit an RFQ with your target quantity and target price; we will confirm availability and lead time from our independent distribution channels. No stock level is published here — pricing and delivery are quoted per order.

What is the frequency stability of DSC400-3333Q0094KE1?

±50 ppm across the full -20°C to 70°C range. That is tight enough for most 1 GbE and PCIe Gen 1/2 reference clocks; for Gen 3 or 25 GbE you would typically look for ±25 ppm or better.

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

The DSC400 series shares the same 20-VFQFN footprint and pinout across multiple frequency configurations. A different ordering code (same base number DSC400) with the same supply and output type will drop in — confirm the output frequencies match your clock tree before swapping.
