ICS87974I
LOW SKEW, 1-TO-15,
LVCMOS/LVTTL CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS87974I is a low skew, low jitter 1-to-15
LVCMOS/LVTTL Clock Generator/Zero Delay
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 ad-
dition, 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. The ICS87974I
is pin for pin compatible with the MPC974.
Guaranteed low jitter and output skew characteristics make the
ICS87974I ideal for those applications demanding well defined
performance and repeatability.
