The DSC1001CL5-033.3330T is a MEMS-based XO (Standard) from Microchip Technology's DSC1001 series, delivering a 33.333 MHz CMOS output with ±10 ppm frequency stability across the full -40 to 105°C industrial-automotive temperature range. Supply voltage spans 1.8V to 3.3V, so it runs from a 1.8V core rail or a 3.3V I/O rail without a separate regulator — one BOM line covers both power domains.
Housed in a 4-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm — this is a standard 3.2 x 2.5 mm oscillator footprint that matches many quartz XO land patterns, so a layout designed for a quartz part can take this MEMS part without a board spin.
