MEMS XO for extended temperature timing
The DSC1101CM5-027.0000T is a 27 MHz MEMS-based oscillator from Microchip's DSC1101 series, delivering CMOS output with ±10 ppm frequency stability across the full -55°C to 125°C military temperature range. The MEMS resonator gives it inherent immunity to the shock and vibration that would pull a quartz crystal off frequency in avionics or downhole instrumentation.

6-SMD footprint and board integration
The 6-SMD no-lead package measures 3.20 mm x 2.50 mm with a seated height of 0.90 mm max. The 2.25–3.6 V supply range means the same decoupling scheme (0.1 µF + 1 µF ceramic) works across both 2.5 V and 3.3 V rails.
