The DSC1121AL2-020.0000 is a 20 MHz MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a CMOS output with ±25 ppm frequency stability over a 2.25V to 3.6V supply range.
The 6-SMD, No Lead Exposed Pad package (7.00mm x 5.00mm, 0.90mm seated height) uses a standard MEMS oscillator footprint; the exposed pad should be connected to a quiet ground plane for thermal and electrical performance.
This makes it suitable for under-hood and cabin electronics.
