ICS8745I
1:5 DIFFERENTIAL-TO-LVDS
ZERO DELAY CLOCK GENERATOR
GENERAL DESCRIPTION
The ICS8745I is a highly versatile 1:5 LVDS
clock generator and a member of the
HiPerClockS family of High Performance Clock
Solutions from ICS. The ICS8745I has a fully in-
tegrated PLL and can be configured as zero
delay buffer, multiplier or divider, and has an output frequency
range of 31.25MHz to 700MHz. The Reference Divider, Feed-
back Divider 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: LVDS, LVPECL, LVHSTL, SSTL, HCSL
Output frequency range: 31.25MHz to 700MHz
Input frequency range: 31.25MHz to 700MHz
VCO range: 250MHz to 700MHz
External feedback for “zero delay” clock regeneration
with configurable frequencies
Programmable dividers allow for the following output-to-input
frequency ratios: 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8
Cycle-to-cycle jitter: 25ps (maximum)
Output skew: 40ps (maximum)
Static phase offset: 50ps ± 200ps
3.3V supply voltage
-40°C to 85°C ambient operating temperature
