Product details

The DSC1121CM1-036.0000T is a 36 MHz MEMS-based oscillator from Microchip's DSC1121 series, delivering a CMOS output with ±50 ppm frequency stability across the full -55°C to 125°C military temperature range.

Operating from a 2.25V to 3.6V supply, the oscillator draws a maximum of 22 mA, which is typical for a CMOS-output MEMS oscillator at 36 MHz.

Housed in a 6-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the DSC1121CM1-036.0000T fits the standard 3.2x2.5mm oscillator footprint and is compatible with reflow soldering profiles used for MEMS devices.

Frequently asked questions

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

Yes, the DSC1121CM1-036.0000T is a drop-in replacement for 3.2x2.5mm quartz oscillators with the same pinout (enable/disable on pin 1, ground on pin 2, output on pin 3, Vdd on pin 4). The MEMS construction offers better shock and vibration tolerance, and the ±50 ppm stability matches most quartz specifications. Verify the supply voltage range (2.25V to 3.6V) and output type (CMOS) against your existing quartz part before committing.

Does the DSC1121CM1-036.0000T have an enable/disable function?

Yes, the oscillator includes an enable/disable function on pin 1. When the pin is pulled low, the output is disabled (high-impedance), allowing the oscillator to be gated for power savings or bus sharing.
