Product details

Four 25 MHz outputs from a single MEMS resonator

Supply voltage spans 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator.

Package footprint and board layout notes

Housed in a 20-VFQFN with exposed pad, 5.00 mm × 3.20 mm body — the centre pad must be soldered to a ground plane for thermal relief and mechanical stability. Height is 0.035" (0.90 mm), fitting standard 1.0 mm keep-out zones on dense mixed-signal boards.

Enable/Disable and output control

Status is Active per Microchip — no EOL notice, no NRND flag.

Frequently asked questions

Can DSC400-1111Q0044KI2T replace a standard 25 MHz quartz oscillator?

Yes, if the application needs four 25 MHz LVCMOS clocks from one package. A single quartz can only provides one output; the DSC400 replaces four discrete oscillators with one MEMS device, saving board area and reducing BOM line count. The ±25 ppm stability matches most quartz XO grades.

What is the footprint of DSC400-1111Q0044KI2T?

The package is a 20-VFQFN with exposed pad, body size 5.00 mm × 3.20 mm, height 0.035" (0.90 mm). The exposed pad must be connected to a ground plane — the datasheet provides the recommended land pattern.

Does DSC400-1111Q0044KI2T have an enable/disable function?

Yes, the Enable/Disable function gates all four outputs. When disabled, the outputs go to a high-impedance state — the supply rail remains powered.
