PI6C3991
3.3V High-Speed, Low-Voltage Programmable
Figure 8. Board-to-Board Clock Distribution
Figure 8 shows the PI6C3991 connected in series to construct a zero
skew clock distribution tree between boards. Delays of the down
stream clock buffers can be programmed to compensate for the wire
length (i.e., select negative skew equal to the wire delay) necessary
to connect them to the master clock source, approximating a zero-

quency jitter because of the non-ideal filtering characteristics of the
PLL filter. It is recommended that not more than two clock buffers be
connected in series.
