Product details

The DSC1121CI1-025.0000 is a 25 MHz MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a CMOS output with a wide supply range of 2.25 V to 3.6 V — this single rail covers both 2.5 V and 3.3 V logic domains without an external level translator.

The 6-SMD no-lead package (3.20 mm x 2.50 mm) with a seated height of 0.90 mm is a standard MEMS oscillator footprint — the same land pattern used by SiTime and Abracon MEMS parts, so a board spin for a second-source swap is minimal.

The DSC1121 series is Microchip's current MEMS oscillator platform, so new designs can commit without a last-time-buy window.

Frequently asked questions

Can DSC1121CI1-025.0000 replace DSC1121CI1-020.0000 in the same BOM?

The only difference is the output frequency: 25 MHz vs 20 MHz. The package, supply voltage, output type, temperature range, and AEC-Q100 rating are identical across the DSC1121 series. If the downstream device can accept a 25 MHz clock in place of 20 MHz, the pinout and footprint are a direct swap — no board layout change is needed.
