Outputs are selectable between LVCMOS and LVDS logic levels, with an Enable/Disable function on each channel — useful for gating clocks during system sleep states without an external load switch. Supply voltage spans 2.25 V to 3.6 V — it runs from a 3.3 V or 2.5 V rail without an extra regulator, and the wide tolerance absorbs ripple from a switching supply. ## Frequency stability and package footprint The 20-VFQFN exposed-pad package (5.00 mm x 3.20 mm, 0.90 mm height) requires a thermal via array under the centre pad for heat sinking; the small footprint frees board area for other routing.","metaTitle":"DSC400-1133Q0079KI1 MEMS XO – 4-Output Clock Gen","metaDescription":"Microchip DSC400-1133Q0079KI1 MEMS XO: 100/100/66.666/25 MHz outputs, LVCMOS/LVDS, ±50 ppm, industrial temp.
