Each reel or tube is lot-tracked and verified against the original datasheet parametrics before quoting. Sourced per RFQ; no factory lead time applies. ## Package, footprint, and handling Supplied in tube. The CMOS output swings rail-to-rail into a 15pF load, so no termination resistor is needed for traces under 50mm on a typical 4-layer PCB. The MEMS resonator itself is immune to the vibration-induced phase noise that plagues crystal-based oscillators in fan-tray or motor-drive environments.","metaTitle":"Microchip DSC6121CI2A-00AP MEMS XO, 19.44MHz/25MHz, CMOS","metaDescription":"Microchip DSC6121CI2A-00AP MEMS XO, dual-output 19.44MHz & 25MHz, ±25ppm, -40~85°C, 1.71-3.63V.
