The DSC8121DI2T: Unlike a quartz crystal oscillator, the MEMS resonator is immune to vibration-induced frequency shifts and has a lower susceptibility to the aging drift that quartz exhibits over years — a meaningful reliability advantage for an oscillator that sits on the same board as a motor drive or a high-vibration fan assembly.

Frequently asked questions
Does DSC8121DI2T come pre-programmed to a specific frequency?
No, it ships as a blank device (Blank (User Must Program)). The output frequency must be programmed using Microchip's TimeFlash tool before the part is soldered to the board.
