Output frequencies are fixed at 10 MHz, 27 MHz, 148.5 MHz, and 125 MHz — a common combination for video/broadcast equipment where 148.5 MHz drives the pixel clock and 125 MHz feeds the Ethernet PHY or FPGA fabric. Frequency stability is ±25 ppm across the full -40 to 85°C industrial temperature range, which keeps the 148.5 MHz video clock within a few hundred Hz of nominal — no external VCXO or PLL cleanup needed for most SDI or HDMI links. ## MEMS resonator means no quartz supply risk Supply voltage spans 2.25 V to 3.6 V, so the same order code works on 2.5 V or 3.3 V rails without a separate LDO or level translator. This is a current-production part that can be ordered for new designs and sustained for the long haul.","metaTitle":"DSC400-1111Q0090KI2 MEMS XO – 10/27/148.5/125 MHz LVCMOS","metaDescription":"Microchip DSC400-1111Q0090KI2: MEMS XO, 4 outputs (10, 27, 148.5, 125 MHz), ±25 ppm, -40 to 85°C, 20-VFQFN.
