Product details

Quad-output MEMS oscillator consolidates the clock tree

The DSC400-1111Q0081KE2T generates four independent LVCMOS output frequencies — 27 MHz, 50 MHz, 25 MHz, and 12 MHz — from a single MEMS resonator, replacing up to four discrete quartz oscillators on the board.

Supply range and stability for mixed-voltage systems

Operating from 2.25 V to 3.6 V, the oscillator covers the common 2.5 V and 3.3 V logic rails without an external regulator — the wide input range absorbs rail ripple from a downstream buck converter.

Active lifecycle and commercial temp grade

It fits office equipment, appliance control boards, and indoor telecom gear; not specified for automotive or engine-bay deployment.

20-VFQFN package — layout considerations

Housed in a 20-lead VFQFN with an exposed pad, the package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm.

Frequently asked questions

What is the exact frequency of the DSC400-1111Q0081KE2T?

This quad-output oscillator provides four simultaneous frequencies: 27 MHz on output 1, 50 MHz on output 2, 25 MHz on output 3, and 12 MHz on output 4, all LVCMOS.

Is the DSC400-1111Q0081KE2T RoHS compliant?

The part is listed under the Microchip DSC400 series; RoHS compliance is standard for this series. Confirm the specific compliance certificate in the product documentation or at RFQ.

Can the DSC400-1111Q0081KE2T replace standard quartz oscillators as a drop-in?

The DSC400 is a quad-output MEMS oscillator — it replaces up to four single-output quartz oscillators, but the 20-VFQFN package and pinout differ from standard 4-pin or 6-pin quartz packages. A PCB layout change is required; it is not a pin-for-pin drop-in for a single quartz can.
