Obsolete MEMS XO — last-time-buy sourcing for existing BOMs
The Microchip DSC6101CI2A-033.3300T is an AEC-Q100 qualified MEMS-based oscillator (XO, Standard) producing a 33.33 MHz CMOS output — now listed as Obsolete by the manufacturer. The MEMS resonator core provides jitter performance typical of silicon oscillators while eliminating the quartz crystal start-up time — relevant for applications where the clock must be valid immediately after power-up.
AEC-Q100 qualification and compliance
Rated AEC-Q100, this oscillator meets the automotive IC qualification standard covering temperature grade, reliability stress, and PPAP — suitable for deployment in engine control units, transmission controllers, and ADAS sensor modules where the clock source must survive 85°C ambient and supply transients. The DSC61XX series is a MEMS-based clock family designed as a drop-in replacement for quartz oscillators in the same footprint, offering inherent shock and vibration tolerance over quartz.
