Supply voltage spans 2.5V to 3.3V, so the same part works in a 2.5V FPGA bank or a 3.3V PHY without a separate regulator or a different order code. ## MEMS resonator — shock immunity and fast start-up MEMS oscillators typically survive 50,000 g shock and 70 g vibration, which matters in portable instrumentation, drone avionics, or outdoor telecom cabinets subject to wind-induced vibration. Microchip lists the DSC1223BI1-155M5200 as Active. The 6-VDFN package (5.00mm x 3.20mm, 0.90mm seated height) is a standard MEMS oscillator footprint shared across the DSC1223 family. The same land pattern accepts other frequencies in the series, so a board spin is not required if the clock rate changes.","metaTitle":"DSC1223BI1-155M5200 – 155.52 MHz LVDS MEMS Oscillator","metaDescription":"Microchip DSC1223BI1-155M5200: 155.52 MHz LVDS XO, MEMS resonator, 2.5-3.3V supply, ±50 ppm stability, -40°C to 85°C.
