ICS87974I-01
LOW SKEW, 1-TO-15,
DIFFERENTIAL-TO-LVCMOS / LVTTL CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS87974I-01 is a low skew, low jitter 1-to-15
Differential-to-LVCMOS / LVTTL Clock Generator/
Zero Delay Buffer and is a member of the
HiPerClockSfamily of High Performance Clock
Solutions from ICS. The device has a fully inte-
grated PLL and three banks whose divider ratios can be
independently controlled, providing output frequency relation-
ships of 1:1, 2:1, 3:1, 3:2, 3:2:1. In addition, the external feed-
back connection provides for a wide selection of output-to-
input frequency ratios. The CLK1 and CLK0, nCLK0 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
ICS87974I-01 ideal for those applications demanding well de-
fined performance and repeatability.
FEATURES
Fully integrated PLL
15 single ended 3.3V LVCMOS / LVTTL outputs
