Comments and Recommendations
Decoupling Capacitor: A decoupling capacitor of 0.1ȝF must be used between all VDD and VSS pins. Place the
capacitor on the component side of the PCB as close to the VDD pin as possible. The PCB trace to the VDD pin and
to the GND via should be kept as short as possible. Do not use vias between the decoupling capacitor and the VDD
pin.
Series Termination Resistor: A series termination resistor is recommended if the distance between the output
clocks and the load is over 1 ½ inch. Place the series termination resistors as close to the clock outputs as possible.
