Product details

25 MHz clock for harsh environments

The DSC1121NM1-025.0000 is a 25 MHz MEMS-based oscillator in a 6-SMD no-lead package (7.0×5.0×0.9 mm). That temperature span covers military avionics, downhole drilling tools, and under-hood automotive ECUs — places where a quartz crystal would fracture under shock or drift beyond ±50 ppm over temperature. The MEMS resonator survives 50,000 g shock and high vibration, making this oscillator a fit for drivetrain-mounted modules, engine bay ECUs, and satellite payloads where a quartz can fails.

Enable/Disable pin for power gating

Active current draw is 35 mA max; disabling the output drops it to 22 mA max — a 37 % reduction that matters in battery-backed or always-on automotive modules. The pin logic is active-high enable (typical for this series) — tie the pin high or leave floating for normal operation; pull low to stop the output and reduce supply current.

Lifecycle and sourcing through independent distribution

The DSC1121 series includes other 25 MHz variants with different stability or temperature grades; verify the BOM position before substituting.

Frequently asked questions

Is the DSC1121NM1-025.0000 AEC-Q100 qualified?

Yes. The DSC1121NM1-025.0000 carries an AEC-Q100 rating, which means it has passed automotive-grade reliability stress tests including temperature cycling, ESD, and latch-up.

What is the output frequency and supply voltage of the DSC1121NM1-025.0000?

The output frequency is 25 MHz with a CMOS output. The supply voltage range is 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V logic rails without a separate regulator.

Does the DSC1121NM1-025.0000 have a direct replacement or cross reference?

Microchip does not list a pin-compatible second source or direct replacement for this exact order code. The DSC1121 series includes other 25 MHz variants with different stability or temperature grades — confirm the BOM position before substituting.
