Product details

The DSC1001CI2-040.0000 is a 40 MHz MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a CMOS output with ±25ppm frequency stability. Operating from 1.8V to 3.3V, this oscillator covers the common logic supply rails — 1.8V, 2.5V, and 3.3V — without needing an external regulator, simplifying the power tree for MCU, FPGA, or Ethernet PHY reference clocks.

Housed in a 4-SMD, No Lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm, the DSC1001CI2-040.0000 is a standard surface-mount footprint compatible with reflow soldering profiles used for ceramic and plastic-packaged oscillators.
