Supply voltage spans 2.25 V to 3.6 V, so it runs from a 2.5 V or 3.3 V rail without a separate regulator; the Enable/Disable function lets the system gate the clock for power savings during idle frames. Rated for -40°C to 85°C, the oscillator holds ±25 ppm stability across the full range — enough margin for a 148.5 MHz receiver PLL that budgets 100 ppm total jitter. Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the thermal pad must be soldered to a ground plane for the MEMS die to reach its rated stability; the 0.50 mm pitch QFN demands a solder-paste stencil aperture matched to the datasheet land pattern. Microchip lists the DSC400-3333Q0089KI2 as Active.","metaTitle":"DSC400-3333Q0089KI2 MEMS XO – LVDS, 148.35/148.5 MHz, Active","metaDescription":"Microchip DSC400-3333Q0089KI2: MEMS XO, LVDS output, dual frequencies 148.35 & 148.5 MHz, ±25 ppm, -40 to 85°C, 20-VFQFN.
