The DSC1001BL1-027.0000T is a 27 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±50 ppm frequency stability across -40°C to 105°C.
The 1.8V to 3.3V supply range lets it run from a common 3.3V or 1.8V rail without an extra regulator — one less component on the BOM.
Yes, it is a direct functional replacement for a 27 MHz quartz XO with CMOS output, but the MEMS base resonator is more shock and vibration tolerant — a real advantage in automotive or industrial environments where quartz can suffer micro-cracks. The ±50 ppm stability matches many standard quartz specs, but confirm your board's load capacitance and drive-level requirements; the MEMS part does not require external load capacitors.
