The CMOS output swings rail-to-rail into a standard 15 pF load. For a CAN bus or Ethernet clock at 27 MHz, ±50 ppm keeps the bit timing within the 1% tolerance window without external trimming. 6-SMD, No Lead package, 5.00mm x 3.20mm body, 0.90mm seated height. The no-lead footprint has castellations on the package edge — the PCB land pattern is a simple 6-pad array with a 2.00mm pitch. No thermal pad; no via-in-pad required. The Enable/Disable pin floats high internally if left open. The DSC1121 series is Microchip's current-production MEMS oscillator family. No pin-compatible second source identified from other manufacturers — the MEMS die and ASIC are Microchip proprietary.","metaTitle":"DSC1121BM1-027.0000 MEMS XO – 27 MHz, -55°C to 125°C","metaDescription":"Microchip DSC1121BM1-027.0000: 27 MHz MEMS XO, CMOS output, ±50 ppm stability, -55°C to 125°C, AEC-Q100.
