The DSC1101AE1-011.0000 is a standard MEMS-based XO from Microchip's DSC1101 series, delivering an 11 MHz CMOS clock with ±50 ppm frequency stability. Runs from a 2.25V to 3.5V supply, covering both 2.5V and 3.3V logic rails without an extra regulator. The Standby (Power Down) pin lets the system cut the oscillator current entirely when the clock is unused — useful for battery-powered or duty-cycled designs.
Temperature grade and commercial deployment
Rated -20°C to 70°C — a commercial temperature band that covers office equipment, indoor appliances, and consumer electronics, but not outdoor or under-hood environments. The ±50 ppm stability holds across this range; for a 11 MHz clock that translates to about 550 Hz worst-case drift — fine for UART baud rates and MCU core clocks, but verify against a tight timing budget like USB full-speed.
Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — standard footprint for 7x5 XO packages; the exposed pad provides a thermal path to the PCB ground plane. Supplied in tube; the 35mA max supply current is the peak draw during active oscillation, not the standby current.
