The DSC1033CC1-020.0000 is a MEMS-based XO (Standard) oscillator delivering a 20 MHz CMOS output from a 3.3 V supply rail. The 3 mA typical supply current (3 mA max) keeps the power budget low for always-on clock trees.
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm.
Yes — the output is CMOS, which means it drives standard CMOS logic inputs directly. The 20 MHz square wave is compatible with MCU clock inputs, FPGA clock pins, and most digital logic families that accept a 3.3 V CMOS clock.
Microchip does not list a direct pin-compatible alternative for this exact order code. The DSC1033 series includes other frequencies and stability grades in the same 4-SMD package — if you need a different frequency or tighter stability, check the DSC1033 family. For a same-frequency replacement, the DSC1033CC1-020.0000 is the only variant at 20 MHz with ±50 ppm and 3.3 V in this package.
