Product details

Active MEMS oscillator — four clocks from one package

It operates from a 2.25 V to 3.6 V supply rail and delivers ±50 ppm frequency stability over the -20°C to 70°C commercial temperature range.

20-VFQFN layout — exposed pad matters

The exposed thermal pad requires a via-in-pad arrangement for proper solder joint reliability and thermal dissipation. The 0.50 mm pitch QFN footprint needs a 4-layer board for clean fan-out of the 20 terminals.

Listed as Active with no end-of-life notice from Microchip.

Frequently asked questions

How can I order the DSC400-1111Q0085KE1T and check availability?

The DSC400-1111Q0085KE1T is an active-production part. We source it through independent distribution channels and quote it to order against your BOM quantity. Availability and current pricing are confirmed at the time of RFQ — no stock-holding claim is made on this page.

Is the DSC400-1111Q0085KE1T equivalent to a standard quartz oscillator?

Functionally yes — it provides the same LVCMOS clock outputs as a quartz XO. Structurally no: it uses a MEMS resonator instead of a quartz crystal, and the 20-VFQFN package with exposed pad is not pin-compatible with a 4-pin or 6-pin quartz oscillator. A board layout change is required to swap between the two.

Does the DSC400-1111Q0085KE1T have an enable/disable function?

Yes — the function is listed as Enable/Disable. This allows individual output channels to be gated under firmware control, reducing power consumption in idle states without removing the supply rail.
