MEMS oscillator for 12 MHz CMOS clock rail
The DSC1033BE2-012.0000T is a 12 MHz XO (Standard) oscillator built on a MEMS resonator rather than a quartz crystal — the base resonator is MEMS, which eliminates the quartz start-up uncertainty and gives a deterministic enable time. 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.
