Clock Multiplication
selected by the tri level select inputs [Sel0, Sel1, Sel2].
NB3N3020 has a LVTTL/LVCMOS output [CLK1] and a
LVPECL clock output [CLK2, CLK2].
Output Enable
tri−state the outputs. OE1 controls the CLK1 clock output
where as OE2 controls the CLK2, CLK2 clock outputs.
When OE1or OE2 are disabled, the respective clock
output(s) are tri−stated. In this mode of operation, PLL is
still running, with the respective clock outputs tri−stated.
When the OE1 or OE2 are enabled, the clock outputs
