MEMS oscillator replaces quartz at 26 MHz
The DSC1121BI1-026.0000 is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a 26 MHz CMOS output from a 6-SMD no-lead package measuring 5.00mm x 3.20mm. The MEMS resonator eliminates the quartz crystal's startup time and vibration sensitivity — a direct swap for a standard 26 MHz crystal oscillator on the same PCB footprint, with the added benefit of a wider supply range (2.25V to 3.6V) that covers 2.5V and 3.3V logic rails without a separate regulator.
Automotive-grade reliability and temperature range
For battery-powered or thermal-constrained designs, that 13 mA saving per oscillator adds up across multiple clock domains.
Microchip lists the DSC1121BI1-026.0000 as Active.
