Product details

MEMS-based timing for harsh environments

The DSC1121CM1-036.0000 is a 36 MHz MEMS-based XO from Microchip's DSC1121 series. The CMOS output directly drives digital logic without an external level translator.

Military temperature qualification

This covers avionics cold-soak at altitude, downhole tool heat, and satellite thermal cycling.

Wide supply tolerance and enable control

Supply voltage range is 2.25V to 3.6V — the oscillator runs directly from a 2.5V or 3.3V rail without an intermediate regulator.

Compact package and active lifecycle

Housed in a 6-SMD No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm — fits tight PCB layouts. The product status is Active, meaning Microchip continues manufacturing this order code with no planned discontinuation. No last-time-buy pressure on this BOM line.

Frequently asked questions

Can DSC1121CM1-036.0000 replace a standard 36 MHz quartz oscillator?

Functionally yes — it outputs a 36 MHz CMOS clock. The MEMS base resonator is more resistant to vibration and thermal shock than quartz, but the pinout and footprint must match the 6-SMD No Lead land pattern of the original quartz oscillator. Verify the existing board's pad layout before substituting.

What supply voltage does DSC1121CM1-036.0000 require?

It operates from 2.25V to 3.6V. A 3.3V rail is well within range, as is a 2.5V rail. No external regulator is needed if the supply is within that window.
