Each output can be configured as LVCMOS or LVDS, so the same part serves both single-ended clock trees and differential SerDes reference inputs without an external level translator. A 2.25 V to 3.6 V supply rail means the oscillator can run directly from a 2.5 V or 3.3 V rail without an extra LDO — one less component on the power tree. Supplied in tape & reel (TR) — the 20-VFQFN exposed pad package is JEDEC-standard for automated pick-and-place.","metaTitle":"DSC400-1133Q0079KI2T MEMS XO – Quad Output","metaDescription":"Microchip DSC400-1133Q0079KI2T MEMS XO, 4 outputs: 100 MHz, 100 MHz, 66.666 MHz, 25 MHz.
