The MEMS base resonator provides the timing reference, eliminating the quartz crystal and its associated start-up time and shock sensitivity. ## Industrial temperature grade and 3V supply The 3V supply rail is common in low-power digital systems; confirm the downstream device's input threshold is compatible with CMOS levels at 3V. ## Standby function and low-power disable Typical active current is 4mA — useful for battery-powered or intermittently operated equipment where the oscillator can be gated off between active periods. ## Compact 4-SMD No Lead footprint Housed in a 2.50mm x 2.00mm 4-SMD No Lead package, 0.90mm seated height. The small footprint demands careful PCB layout — ensure the pad geometry matches the land pattern recommended in the datasheet, and that the solder paste stencil aperture is sized for the 0.50mm pitch typical of this package class.","metaTitle":"DSC1030DI1-042.5000T MEMS Oscillator 42.5 MHz CMOS -","metaDescription":"DSC1030DI1-042.5000T XO (Standard) MEMS oscillator, 42.5 MHz CMOS output, 3V supply, -40°C to 85°C, 4-SMD.
