Comments and Recommendations
Decoupling Capacitor:
A decoupling capacitor of 0.1μF must be used between 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 inch. The nominal impedance of the clock outputs is given in the Operating Condition
Tables. Place the series termination resistors as close to the clock outputs as possible.
Zero Delay and Skew Control: All outputs and CLKIN pins should be loaded with the same load to achieve “Zero
Delay” between the CLKIN and the outputs. The FBK pin is connected to PLL internally on-chip for feedback and
should be connected to one of to output clocks externally. For applications requiring zero input/output delay, the load
at the all output pins including the FBK pin must be the same. If any delay adjustment is required, the capacitance at
the FBK pin could be increased or decreased to increase or decrease the delay between Bank A and B clocks
relative to CLKIN. For minimum pin-to-pin skew, the external load at all the Bank A and B clocks must be the same.
In addition, the rise and fall time of the reference clock at CLKIN pin should be similar to rise and fall times at the
CLKA and CLK B bank outputs.
