The MEMS die and the PLL are inside the same package, so the output jitter is set by the on-chip regulator, not by external supply noise coupling through the Vdd pin. ## Lifecycle status and sourcing posture For existing BOM lines that call out this exact order code, independent surplus and broker inventory is the remaining supply path.","metaTitle":"Microchip DSC6122CI2A-00AST XO, 20/25MHz, CMOS, 4-VDFN","metaDescription":"Microchip DSC6122CI2A-00AST MEMS XO (Standard), dual 20MHz & 25MHz CMOS outputs, ±25ppm stability, -40°C~85°C.
