The DSC1001BI2-020.0000T is a 20 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, delivering a CMOS output in a 4-SMD no-lead package.
Supply voltage spans 1.8 V to 3.3 V, so the same BOM line can serve 1.8 V MCU domains and 3.3 V peripheral rails without a separate level translator on the clock input.
Functionally yes — it provides the same 20 MHz CMOS output in a 4-SMD no-lead footprint. The MEMS resonator offers better shock and vibration immunity than quartz, which matters for automotive and industrial environments. Confirm the supply voltage range (1.8 V to 3.3 V) and the standby function pinout match your existing oscillator before substitution.
Maximum standby current is 15 µA when the device is in power-down mode. This allows the oscillator to be disabled during system sleep, reducing overall power draw in battery-powered or energy-harvesting designs.
