Product details

The DSC1121CI1-125.0000T is a 125 MHz MEMS-based oscillator from Microchip's DSC1121 family, delivering a CMOS output from a 2.25V to 3.6V supply rail.

Supply range, output, and enable/disable control

The 2.25V to 3.6V supply covers 2.5V and 3.3V logic rails without an external regulator — one less component on the BOM.

The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm footprint shared by many MEMS and quartz oscillators, so the PCB layout can accept alternate suppliers without a spin. Surface-mount assembly with no through-hole leads; the small footprint suits space-constrained automotive modules like camera or radar sensor boards.

Sourced through independent distribution against the BOM quantity.

Frequently asked questions

Is the DSC1121CI1-125.0000T AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, which means it meets automotive-grade reliability stress and temperature qualification. Suitable for under-hood or cabin-mounted electronics where extended temperature and vibration are present.

Does the DSC1121CI1-125.0000T have an enable/disable function?

Yes, the part includes an enable/disable function. When disabled, the maximum supply current drops to 22 mA from the 35 mA active maximum.
