Operational Mode Descriptions
Figure 2. Zero-Skew and/or Zero-Delay Clock Driver
Figure 2 shows the SuperClock configured as a zero-skew clock
buffer. In this mode the PI6C3991 can be used as the basis for a low-
skew clock distribution tree. When all of the function select inputs
(xF0, xF1) are left open, the outputs are aligned and may each drive
a terminated transmission line to an independent load. The FB input

can be tied to any output in this configuration and the operating
frequency range is selected with the FS pin. The low-skew specifi-
cation, coupled with the ability to drive terminated transmission lines
(with impedances as low as 50 Ohm), allows efficient printed circuit
board design.
