Supply voltage spans 2.25V to 3.63V, so it runs from a 2.5V or 3.3V rail without an external regulator. ## Stability and package for board-level fit Frequency stability is ±10 ppm across temperature, voltage, and load — tight enough for a 156.25 MHz serial clock without external trimming. The 6-SMD no-lead package (3.20 mm x 2.50 mm, 0.90 mm seated height) fits the same footprint as a standard quartz oscillator, so a board designed for a quartz can take this MEMS part without a layout change. Microchip lists the DSC1123CI5-156.2500T as Active.","metaTitle":"DSC1123CI5-156.2500T Microchip MEMS XO, 156.25 MHz LVDS","metaDescription":"Microchip DSC1123CI5-156.2500T MEMS oscillator: 156.25 MHz LVDS output, ±10 ppm stability, 2.25V-3.63V supply, -40°C to 85°C.
