The DSC1101CI2-066.6667 is a MEMS-based XO (Standard) from Microchip's DSC1101 series, delivering a 66.6667 MHz CMOS clock with ±25 ppm frequency stability across -40°C to +85°C. Supply voltage spans 2.25V to 3.6V, covering 2.5V and 3.3V rails without an external regulator — the CMOS output swings rail-to-rail, so the logic-high level matches the supply.
Active lifecycle — no EOL concern for new designs
The MEMS resonator construction avoids quartz supply constraints and offers better shock/vibration tolerance than a crystal oscillator — relevant for equipment exposed to mechanical stress.
