Product details

Four clocks from one MEMS die

The DSC400-1111Q0084KE1 is a MEMS-based XO that replaces up to four discrete oscillators with a single 20-VFQFN part — outputs 33.3333 MHz, 50 MHz, 125 MHz, and 100 MHz in LVCMOS logic levels.

MEMS reliability, quartz-like stability

20-VFQFN package and board fit

Housed in a 5.00 mm x 3.20 mm, 20-lead VFQFN with an exposed pad — the pad needs a thermal via array under it to pull heat into the ground plane, and the 0.50 mm pitch demands careful fan-out on a two-layer board.

Frequently asked questions

What frequencies does the DSC400-1111Q0084KE1 output?

Four LVCMOS outputs: 33.3333 MHz, 50 MHz, 125 MHz, and 100 MHz. The frequencies are factory-programmed and not field-adjustable.

Is this a MEMS oscillator?

Yes — the base resonator is MEMS, not quartz. That means faster startup, better shock tolerance, and no crystal aging drift over the first year.

What is the closest pin-compatible alternative to the DSC400-1111Q0084KE1?

No direct pin-compatible alternative is listed in the DSC400 series with the same four-frequency set. Other DSC400 order codes share the same package and pinout but differ in output frequencies — check the DSC400 family table for a frequency combination that matches your BOM.
