The DSC1001CE1-020.8300T is a MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a 20.83 MHz CMOS output. The supply voltage range spans 1.8V to 3.3V, so the same part can be used across 1.8V, 2.5V, or 3.3V logic rails without a separate regulator for the oscillator.
Standby power-down and current draw
For an automotive ECU that sleeps between ignition cycles, that standby current is well below the module's quiescent budget.
Housed in a 4-SMD no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, the footprint matches standard 3.2 x 2.5 mm oscillator pads.
