GENERAL DESCRIPTION
The ICS87974I is a low skew, low jitter 1-to-15 LVCMOS/LVTTL Clock Generator/Zero Delay HiPerClockS™ Buffer and is a member of the HiPerClockS family of high performance clock solutions from ICS. The device has a fully integrated PLL and three banks whose divider ratios can be independently controlled, providing output frequency relationships of 1:1, 2:1, 3:1, 3:2, 3:2:1. In addition, the external feedback connection provides for a wide selection of output-to-input frequency ratios. The CLK0 and CLK1 pins allow for redundant clocking on the input and dynamically switching the PLL between two clock sources.
