The DSC1001DI5-040.0000T is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a fixed 40 MHz CMOS output with ±10 ppm frequency stability. The 1.8V to 3.3V supply range lets it run directly from a common 3.3V or 1.8V rail without an intermediate regulator, simplifying the power tree.
Package, footprint, and supply considerations
Housed in a 4-SMD, No Lead package measuring 2.50 mm x 2.00 mm with a seated height of 0.90 mm, the DSC1001DI5-040.0000T fits compact PCB layouts common in automotive ECUs and sensor nodes. The surface-mount footprint requires standard reflow soldering; no special via-in-pad or thermal management is needed given the 7.2 mA max supply current. The base product number DSC1001 covers the series; the full order code DSC1001DI5-040.0000T encodes the specific frequency, stability grade, and packaging variant.
