should be provided with an extremely low impedance path to the V
Input/Output Power
This source supplies power for the I/O buffers. The user must provide adequate external decoupling
capacitors.

and the input should be provided with an extremely low impedance path to the V
System Ground
An isolated ground for the internal processing logic and I/O buffers. This connection must be tied
externally to all chip ground connections, except GND
decoupling capacitors.
System PLL Ground
Ground dedicated for system PLL use. The connection should be provided with an extremely
low-impedance path to ground.
