Product details

MEMS XO with three 100 MHz HCSL lanes

Why three HCSL outputs matter for your BOM

Each of the three outputs is rated at 100 MHz with HCSL signalling, the same logic family used for PCIe reference clocks. The Enable/Disable function lets firmware gate each output independently, useful for power-sequencing or test-mode isolation without external load switches.

The wide supply range (2.25 V to 3.6 V) means this oscillator works across 2.5 V and 3.3 V rails without a separate regulator, simplifying power-tree planning.

Frequently asked questions

Where can I buy the DSC400-0444Q0009KI1 and how is it quoted?

This is an active Microchip part available through independent distribution. Quoted to order against your BOM quantity — no minimum buy-in, no stock-holding claim. Request an RFQ for current lead time and pricing.

What is the pin-compatible alternative to the DSC400-0444Q0009KI1 in the same family?

The DSC400-0444Q0009KI0 shares the same 20-VFQFN package and output count but may differ in frequency plan or stability grade. Confirm the output frequencies and stability spec against your design before substituting.

Does the DSC400-0444Q0009KI1 have a datasheet?

Yes — the full datasheet for the DSC400 series is published by Microchip. It covers the MEMS resonator architecture, HCSL output timing, jitter performance, and the Enable/Disable timing diagram. Request a copy with your RFQ.
