The DSC6001ML3B-026.0000T is a standard MEMS-based oscillator (XO) delivering a 26 MHz CMOS output from a 4-VFLGA package that measures 2.00mm x 1.60mm — about the size of a grain of rice. AEC-Q100 qualification puts this oscillator in the automotive temperature grade band — it is rated for under-hood and cabin environments where the ambient can hit 125 °C. The wide supply range of 1.71V to 3.63V means it can run directly off a 1.8V or 3.3V rail without a separate regulator, simplifying the power tree.

The 4-VFLGA package is a land-grid array with no leads — the pads are on the bottom of the package. Reworking it means hot air from underneath or a preheater, plus careful alignment because the pads are hidden. The 0.89 mm seated height is low enough to fit under a shield can.
