Resources for 87974I
Description
The 87974I is a low skew, low jitter 1-to-15 LVCMOS/ LVTTL Clock Generator/Zero Delay Buffer. 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. Guaranteed low jitter and output skew characteristics make the 87974I ideal for those applications demanding well defined performance and repeatability.
