General Description
The ICS874S02I is a highly versatile 1:1 Differential-
to-LVDS Clock Generator and a member of the
HiPerClockS family of High Performance Clock
Solutions from IDT. The ICS874S02I has a fully
integrated PLL and can be configured as a zero
delay buffer, multiplier or divider, and has an output frequency
range of 62.5MHz to 1GHz. The reference divider, feedback
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
One differential LVDS output pair and
one differential feedback output pair
One differential clock input pair
CLK/nCLK can accept the following differential input levels:
LVPECL, LVDS, LVHSTL, SSTL
Input frequency range: 62.5MHz to 1GHz
Output frequency range: 62.5MHz to 1GHz
VCO range: 500MHz - 1GHz
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: 35ps (maximum)
Static phase offset: ±100ps
Full 3.3V supply mode
-40°C to 85°C ambient operating temperature
Available in standard (RoHS 5) package
