The DSC1001DI5-040.0000 is a 40 MHz MEMS-based XO (Standard) delivering a CMOS output — a direct-fit clock source for automotive ECUs, industrial controllers, and communications modules that need a clean square-wave clock without a separate crystal and load caps. Frequency stability is held to ±10 ppm across the -40 to 85°C industrial range, which keeps the system clock within tight timing margins for CAN, LIN, and Ethernet PHY reference clocks.
The oscillator operates from a single 1.8V to 3.3V supply, covering the common digital core and I/O rails without needing a dedicated LDO for the clock source.
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 compact footprint that fits space-constrained PCB layouts common in automotive sensor modules and portable instrumentation.
