The DSC1001DI1-038.4000 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a fixed 38.4 MHz CMOS output — a common reference frequency for automotive Ethernet, CAN-FD controllers, and high-speed serial interfaces.
Supply voltage and stability margins
Operates from 1.8V to 3.3V — a single BOM line covers 1.8V, 2.5V, and 3.3V logic rails without a separate voltage regulator.
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm — a standard 2.0 x 2.5 mm footprint that matches many MEMS and quartz oscillators. Surface-mount, supplied in tube — the no-lead package has solder pads on the bottom; ensure the PCB land pattern follows the manufacturer's recommended footprint for reliable reflow.
