The supply voltage covers 1.8V to 3.3V, so the same part can serve a 1.8V MCU core clock and a 3.3V peripheral bus — one BOM line for both rails. For a 27 MHz clock, this keeps the timing error under 675 Hz worst-case — tight enough for a CAN or USB full-speed interface without external trim. In a battery-backed ECU that sleeps between ignition cycles, this standby draw is below the module's own leakage floor. The 4-SMD, no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm. This footprint is common across the DSC1001 family, so a single PCB layout can accommodate multiple frequency variants.","metaTitle":"DSC1001CI2-027.0000B MEMS Oscillator – 27 MHz, CMOS","metaDescription":"Microchip DSC1001CI2-027.0000B: 27 MHz XO, CMOS output, ±25 ppm stability, AEC-Q100 qualified, -40°C to 85°C.
