The DSC400-0103Q0102KI1 is a MEMS-based XO that delivers two fixed output frequencies from a single 20-VFQFN package: 148.5 MHz and 14.7456 MHz. The 148.5 MHz rail is the standard pixel clock for 1080p video at 60 Hz; the 14.7456 MHz output covers common UART baud rates and audio serial clocks. Using one device instead of two separate oscillators saves board space and reduces BOM line count.
