DESCRIPTION
The PCK2002PL is a 1–4 fanout buffer used as a high-performance,
low skew, general purpose and PCI-X clock buffer . It distributes one
input clock (BUF_IN) signal to four output clocks (BUF_OUT

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability .
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
