66 MHz MEMS XO with AEC-Q100 rating
The DSC1001CE1-066.0000T is a 66 MHz MEMS-based oscillator from Microchip's DSC1001 series, delivering a CMOS output with ±50 ppm frequency stability across a -20°C to 70°C operating range. Rated AEC-Q100, this part is qualified for automotive applications — the MEMS resonator and CMOS drive stage are tested to the stress and reliability requirements of the automotive IC qualification standard.
Supply flexibility and standby power
The supply voltage range spans 1.8V to 3.3V — a single BOM line covers 1.8V, 2.5V, or 3.3V clock domains without a separate regulator or level translator. A standby (power-down) function drops the supply current to 15 µA max, letting the oscillator gate its own power draw when the downstream logic is idle. Active current draw is 7.2 mA max at 66 MHz, which keeps the thermal contribution low in a sealed 4-SMD package.
Active lifecycle and sourcing
Sourced through independent distribution, quoted to order against the BOM quantity.
