ICS8745
1:5 DIFFERENTIAL-TO-LVDS
ZERO DELAY CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS8745 is a highly versatile 1:5 LVDS Clock
Generator and a member of the HiPerClockS
family of High Performance Clock Solutions from
ICS. The ICS8745 has a fully integrated PLL and
can be configured as zero delay buffer, multi-
plier or divider, and has an output frequency range of
31.25MHz to 700MHz. The Reference Divider, Feedback Di-
vider and Output Divider are each programmable, thereby
allowing for the following output-to-input frequency ratios:
8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8. The external feedback allows
the device to achieve “zero delay” between the input clock
and the output clocks. The PLL_SEL pin can be used to
bypass the PLL for system test and debug purposes. In
bypass mode, the reference clock is routed around the PLL
and into the internal output dividers.
FEATURES
5 differential LVDS outputs designed to meet
or exceed the requirements of ANSI TIA/EIA-644
Selectable differential clock inputs
CLKx, nCLKx pairs can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL
Output frequency range: 31.25MHz to 700MHz
Input frequency range: 31.25MHz to 700MHz
VCO range: 250MHz to 700MHz
