The DSC6101CI1A-026.0000T: The four pads are supply, ground, output, and enable; no external load capacitors are needed because the MEMS resonator is self-contained.
Sourcing reality for an obsolete MEMS oscillator
Because the DSC61XX series shares a common 4-SMD footprint and supply architecture, a parametric search for a 26 MHz MEMS oscillator with CMOS output and AEC-Q100 qualification in the same package will yield drop-in candidates from the same family or from competitors — but each must be validated for pinout and enable polarity before substitution.
