Product details

MEMS oscillator with full military temperature range

The DSC1101CM1-033.3333T is a MEMS-based XO from Microchip's DSC1101 series, delivering a 33.3333 MHz CMOS output with ±50 ppm frequency stability across the full -55°C to 125°C military temperature range. The 2.25V to 3.6V supply range covers both 2.5V and 3.3V logic rails with margin, so a single BOM line can serve multiple voltage domains without separate order codes.

Standby power-down saves 35 mA when idle

This makes the part suitable for battery-powered or intermittently-operated systems where the clock must be gated off to conserve energy.

Frequently asked questions

Does DSC1101CM1-033.3333T have a standby or power-down feature?

Yes, it has a Standby (Power Down) function that reduces supply current from 35 mA maximum to 95 µA maximum when the output is disabled.

Is DSC1101CM1-033.3333T a direct replacement for older quartz oscillators?

It can replace a quartz-based XO in the same 6-SMD no-lead footprint, but the MEMS resonator eliminates load-capacitance matching and offers better shock/vibration tolerance. The output is CMOS, so the load interface must be compatible.
