Product details

Dual-output MEMS oscillator for extreme-temperature timing

The DSC2311KM2-R0005T is a MEMS-based XO delivering two 20 MHz CMOS clock outputs from a single resonator, with ±25 ppm frequency stability across the full -55°C to +125°C military temperature range. The Enable/Disable function lets each output be gated independently, useful for power-sequencing or test-mode isolation without external logic.

Supply flexibility and package footprint

Operating from 2.25 V to 3.6 V, the oscillator runs on 2.5 V or 3.3 V rails without a separate LDO — one less part in the timing tree. Housed in a 6-VDFN package measuring 2.50 mm x 2.00 mm with a 0.90 mm height, the footprint suits space-constrained boards; the 0.50 mm pitch pads require careful solder-paste stencil design to avoid bridging.

Frequently asked questions

Is the DSC2311KM2-R0005T suitable for high-reliability environments?

Yes — the -55°C to +125°C operating temperature range qualifies it for avionics, downhole instrumentation, and satellite timing applications where commercial-grade oscillators would drift out of spec.

What is the output frequency and stability of the DSC2311KM2-R0005T?

Both outputs are 20 MHz CMOS with ±25 ppm frequency stability over the full temperature range.
