The DSC1001CI1-058.0000T is a 58 MHz XO (Standard) MEMS oscillator from Microchip's DSC1001 series, delivering a CMOS output across a 1.8V to 3.3V supply range.
The 4-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3225 footprint that matches many quartz XO pads without layout changes.
Frequency stability and supply current
Maximum supply current during operation is 7.2 mA; in standby it drops to 15 µA. That 480:1 ratio means the oscillator draws negligible power when the system is parked.
