3.3V LVPECL CLOCK

GENERAL DESCRIPTION  
Features  
10 differential 3.3V LVPECL outputs  
The ICS8732-11 is a low voltage, low skew,  
ICS  
3.3V LVPECL Clock Generator and a member of  
the HiPerClockS™ family of High Performance  
Clock Solutions from ICS. The ICS8732-11 has  
two selectable clock inputs. The CLK0, nCLK0  
Selectable differential CLK0, nCLK0 or  
LVCMOS/LVTTL CLK1 inputs  
HiPerClockS™  
CLK0, nCLK0 supports the following input types:  
LVPECL, LVDS, LVHSTL, SSTL, HCSL  
pair can accept most standard differential input levels.  
The single ended clock input accepts LVCMOS or LVTTL  
input levels.The ICS8732-11 has a fully integrated PLL along  
with frequency configurable outputs. An external feedback  
input and outputs regenerate clocks with “zero delay”.  
CLK1 accepts the following input levels:  
LVCMOS or LVTTL  
Maximum output frequency: 700MHz  
VCO range: 250MHz to 700MHz  
The ICS8732-11 has multiple divide select pins for each bank  
of outputs along with 3 independent feedback divide select  
pins allowing the ICS8732-11 to function both as a frequency  
multiplier and divider. The PLL_SEL input can be used  
to bypass the PLL for test and system debug purposes.  
In bypass mode, the input clock is routed around the PLL  
and into the internal output dividers.  
External feedback for “zero delay” clock regeneration  
with configurable frequencies  
Cycle-to-cycle jitter: CLK, nCLK -TBD  
CLK1 - TBD  
Output skew: TBD  
Static phase offset: TBD
