The DSC6003HA1B-020.0000 is a 20 MHz MEMS-based oscillator (XO) with CMOS output, part of Microchip's DSC60XXB series. The MEMS resonator gives it faster startup and better shock tolerance than a quartz equivalent, and the 1.8V to 3.3V supply range lets it run directly off a 1.8V core rail or a 3.3V I/O rail without a level translator.
Housed in a 4-VFLGA package measuring 1.60mm x 1.20mm with a seated height of 0.89mm, this is a compact surface-mount oscillator.
