The DSC6011HI2B-026.0000 is an active-production MEMS-based XO from Microchip's DSC60XXB series, qualified to AEC-Q100 — the automotive IC reliability standard covering -40°C to +85°C operation and stress tests like temperature cycling and ESD. It delivers a fixed 26 MHz CMOS output with ±25 ppm frequency stability, drawing 1.3 mA typical from a 1.8V to 3.3V supply rail. The 4-VFLGA package (1.60 mm x 1.20 mm footprint, 0.89 mm seated height) suits space-constrained automotive ECUs, ADAS cameras, and infotainment modules where a quartz crystal would consume more board area.
This makes the part suitable for automotive modules that must wake from a sleep state on a CAN or LIN message without a separate enable switch.
No pin-compatible second source or direct replacement is listed by the manufacturer. The DSC60XXB family shares the same footprint and supply range, so a different frequency variant in the series is the closest functional alternative if the 26 MHz output is not required.
