The DSC1001DI4-059.7800T is a fixed-frequency 59.78 MHz XO (Standard) from Microchip's DSC1001 series, built on a MEMS resonator rather than a quartz crystal. It delivers a CMOS output and is qualified to AEC-Q100, making it suitable for automotive and industrial applications where vibration and temperature cycling matter. The 4-SMD, no-lead package measures 2.50 mm x 2.00 mm with a seated height of 0.90 mm, fitting tight board layouts. The supply voltage range spans 1.8V to 3.3V, so it can run off a 1.8V core rail or a 3.3V I/O rail without an extra regulator.
Power budget and standby control
The MEMS resonator inherently handles higher shock and vibration than quartz, which reduces phase-noise degradation in high-g environments.
The package is standard no-lead — no special handling beyond standard MSL precautions.
