Product details

The DSC1121NE5-020.0000 is a 20 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1121 series, delivering a CMOS output with ±10ppm frequency stability across its -20°C to 70°C operating range. The 2.25V to 3.6V supply range allows direct connection to 2.5V or 3.3V rails without an external regulator, and the Enable/Disable function lets the system shut down the oscillator for low-power sleep modes — drawing 22mA max when disabled versus 35mA max when active.

Housed in a 6-SMD, No Lead package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, this oscillator uses a standard 6-pin land pattern common to many MEMS and quartz oscillators — the pad layout matches the industry-standard 7x5 mm footprint, so a board designed for a quartz oscillator in the same form factor can accept this MEMS part without a layout change.

Sourced through independent distribution against the BOM quantity.

Frequently asked questions

Is the DSC1121NE5-020.0000 AEC-Q100 qualified and suitable for automotive use?

Yes, it carries AEC-Q100 qualification. That means it has passed the automotive-grade reliability stress tests — temperature cycling, ESD, latch-up — and is suitable for under-hood or cabin electronic modules that require automotive qualification. The -20°C to 70°C temperature range is commercial grade, so it fits cabin and infotainment domains rather than engine-bay ambient extremes.

What is the closest pin-compatible alternative to the DSC1121NE5-020.0000 in the DSC1121 series?

Any DSC1121-series oscillator with the same 20 MHz frequency, CMOS output, and 6-SMD no-lead package is pin-compatible — the base product number DSC1121 defines the footprint and electrical interface. The suffix (e.g., NE5) encodes the temperature range and stability grade, so a part with a different stability or temperature code but the same package and frequency will drop into the same PCB land pattern.
