Product details

MEMS dual-frequency oscillator for industrial clocks

The DSC2311KI1-R0059 is a MEMS-based XO (Standard) oscillator from Microchip's DSC2311 series, delivering two independent CMOS clock outputs: 25 MHz on output 1 and 12 MHz on output 2. The supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V logic rails without an external regulator.

Sourcing and lifecycle for the DSC2311KI1-R0059

Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, this oscillator fits compact PCB layouts where vertical clearance is tight — think blade servers, portable instruments, or multi-layer stacked boards.

Frequently asked questions

Is the DSC2311KI1-R0059 a drop-in replacement for a standard 25 MHz quartz oscillator?

It is a functional replacement in terms of output frequency and CMOS logic levels, but the 6-VDFN package (2.50 mm x 2.00 mm) differs from common 4-pin quartz oscillator footprints (e.g., 7.0 mm x 5.0 mm or 5.0 mm x 3.2 mm). A PCB layout change is required to accommodate the smaller package and the Enable/Disable pin. The MEMS base also offers faster startup and better shock tolerance than quartz.
