Product details

The DSC1001CC2-012.2880T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 12.288 MHz CMOS output with ±25 ppm frequency stability across its 0°C to 70°C operating range. Rated AEC-Q100, this oscillator suits automotive body electronics, infotainment, and ADAS reference clocks where a quartz crystal's vibration sensitivity or start-up time is a concern.

Supply voltage spans 1.8V to 3.3V, so the same reel serves 1.8V MCU and 3.3V FPGA clock trees without a separate regulator for the oscillator rail.

Frequently asked questions

What is the frequency stability of DSC1001CC2-012.2880T?

For a 12.288 MHz carrier, that's a maximum frequency error of about 307 Hz — tight enough for most UART bit-rate clocks and CAN bus timing without external trimming.

Is DSC1001CC2-012.2880T a direct replacement for a standard quartz crystal oscillator?

Functionally yes — it is a drop-in XO with CMOS output and the same 4-SMD footprint as many quartz oscillators. The MEMS resonator is less sensitive to vibration and shock than a quartz crystal, so it holds frequency better in automotive or portable environments. Pin-compatible with most 4-pin SMD oscillators in the 3.2 mm × 2.5 mm package, but confirm the enable logic polarity on your board.
