The DSC1121AI1-027.0000T is a 27 MHz XO (Standard) MEMS oscillator from Microchip's DSC1121 series, delivering a CMOS output across a 2.25V to 3.6V supply range — it runs from a 2.5V or 3.3V rail without a secondary regulator.
27 MHz exactly, as indicated by the order-code suffix. This is a fixed-frequency oscillator — no programmability.
CMOS output — it drives standard digital logic inputs directly without external level translation.
