The DSC1121AI1-100.0000 is a 100 MHz MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a CMOS output with ±50 ppm frequency stability. Its 2.25V to 3.6V supply range covers both 2.5V and 3.3V rails, so the same oscillator can serve multiple voltage domains on the board without a dedicated LDO.
Active lifecycle—no last-time-buy pressure
Microchip lists the DSC1121AI1-100.0000 as Active.
