grounded on the board. These signals are adjacent to the PLL power and ground signals.
Grounding the tune signals helps shield the PLL power and ground signals.
The PLL tune bits 0, 1, 2 and 3 should have pull up and pull down resistors very close to
the package ball. The pull up should not be populated and the pull down should be
populated with a zero ohm resistor.
