Product details

Four LVPECL clocks from one MEMS oscillator

The DSC400-2222Q0104KE2 is a MEMS-based XO that delivers four independent LVPECL output frequencies: 125 MHz, 100 MHz, 200 MHz, and 156.25 MHz — covering common Ethernet, PCIe, and serial-link reference clock rates from a single 20-VFQFN package.

Supply voltage spans 2.25 V to 3.6 V, so it runs on a 2.5 V or 3.3 V rail without an external regulator — just decouple the pin.

Active and available through distribution

It is a current-design part, not a last-time-buy candidate.

Frequently asked questions

Is DSC400-2222Q0104KE2 compatible with a 3.3V supply?

Yes. The supply voltage range is 2.25 V to 3.6 V, so a 3.3 V rail is within spec. No external regulator needed — just a bypass cap at the supply pin.

What is the closest pin-compatible alternative to DSC400-2222Q0104KE2?

No pin-compatible alternative is listed in the DSC400 series for this exact frequency set. The DSC400 family shares the same 20-VFQFN footprint and supply range, but each order code has a unique output frequency combination. Verify the frequencies your BOM requires before substituting.

What is the output type of DSC400-2222Q0104KE2?

LVPECL — low-voltage positive emitter-coupled logic. It requires 50-ohm termination to Vcc-2V at the receiver end, typical for high-speed clock distribution.
