The DSC1001CE1-033.8688T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a fixed 33.8688 MHz output in CMOS logic levels. The 33.8688 MHz frequency is a common reference for USB, audio codecs, and certain Ethernet controllers — confirm your PLL or clock-tree input before committing the BOM line.
Supply flexibility and standby power discipline
Operating from 1.8V to 3.3V, this oscillator spans multiple logic families without a dedicated regulator — one part number covers 1.8V, 2.5V, and 3.3V rails.
Temperature grade and automotive qualification
Frequency stability is ±50 ppm — adequate for most serial communication and processor clocking; tighter stability requirements (e.g., ±25 ppm) would need a different DSC1001 variant or a temperature-compensated oscillator.
