Product details

MEMS oscillator for extreme environments

A downhole tool or satellite payload that sees 125°C ambient still gets a clean 20 MHz CMOS clock. Supply voltage spans 2.25V to 3.6V, so it runs off a 2.5V or 3.3V rail directly — no extra LDO needed for the oscillator.

Standby function saves battery life

Active production, ready to order

Small 6-VDFN package

Housed in a 6-VDFN measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — fits tight PCB layouts where a standard 5x7 mm oscillator is too large.

Frequently asked questions

Can DSC1101DM1-020.0000T replace a quartz crystal oscillator?

Yes — it is a drop-in XO replacement for a 20 MHz CMOS clock. The MEMS resonator is more rugged than quartz, and the frequency stability is ±50 ppm, comparable to a standard quartz XO. The 6-VDFN footprint is smaller than most quartz oscillators, so check the PCB pad layout.
