A single quartz can only provides one output; the DSC400 replaces four discrete oscillators with one MEMS device, saving board area and reducing BOM line count. The ±25 ppm stability matches most quartz XO grades."},{"question":"What is the footprint of DSC400-1111Q0044KI2T?","answer":"The package is a 20-VFQFN with exposed pad, body size 5.00 mm × 3.20 mm, height 0.035\" (0.90 mm).
