Outputs are configurable as LVCMOS or LVDS per channel — the two 148.35 MHz lanes can drive differential pairs at full speed, while the 27 MHz and 25 MHz run single-ended into the PHY clock inputs without extra level translation. Supply voltage spans 2.25 V to 3.6 V, so a single 3.3 V rail or a 2.5 V rail feeds all four outputs without a dedicated regulator — the internal LDO cleans the rail for the MEMS core. ## Temperature grade and board-fit note","metaTitle":"DSC400-3133Q0080KI1 MEMS XO – 4 Outputs, LVCMOS/LVDS, Active","metaDescription":"Microchip DSC400-3133Q0080KI1: MEMS XO, 4 outputs (148.35/27/25 MHz), LVCMOS & LVDS, ±50 ppm, -40°C to +85°C, 20-VFQFN.
