Output is CMOS, so it drives the clock input of an MCU, FPGA, or digital ASIC directly without an external level translator. Supply voltage is 3.3 V, matching the most common digital core and I/O rail in commercial and industrial systems. ## Frequency stability and operating range Typical supply current is 3 mA while oscillating; in standby (power-down) mode the disable current drops to 1 µA, so the oscillator can be gated off between active periods without draining a battery-backed rail. ## Active production, quoted to order Sourced per RFQ against the BOM quantity. No official successor or second-source listed; the DSC1033 base number covers the family, and the BE2 suffix encodes the 12 MHz ±25 ppm commercial-grade variant.","metaTitle":"DSC1033BE2-012.0000T MEMS XO 12 MHz CMOS 3.3V Active","metaDescription":"Microchip DSC1033BE2-012.0000T XO (Standard) MEMS oscillator, 12 MHz CMOS output, 3.3V, ±25 ppm stability, -20°C to 70°C.
