The DSC1001CI1-026.0000T is a 26 MHz MEMS-based XO (Standard) oscillator from Microchip's DSC1001 series, qualified to AEC-Q100 — the automotive IC reliability standard. The supply range covers all three common voltages, so the same BOM line can serve multiple board variants by changing only the supply rail.
Temperature range and standby power
This is the key spec for battery-backed modules or always-on ECUs that must preserve the coin cell or supercap during ignition-off periods.
The 4-SMD, No Lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm — a standard 3.2 x 2.5 mm footprint shared by many MEMS and quartz oscillators. The no-lead land pattern keeps the parasitic inductance low, which matters for the CMOS edge rate at 26 MHz.
