If the ICs are not mounted to the printed circuit board, the characteristics of ICs may not be fully demonstrated. Mount 0.1µF capacitors in the vicinity of the IC pins between PIN 1&2 and PIN 3, PIN 13 and PIN 14&15, and PIN 17 and PIN 18, respectively. As to the jitters, the TYP values vary with the substrate, power supply, output loads, noises, and others. Also, the operating margin should be thoroughly checked.
