350MHZ, CRYSTAL-TO-LVCMOS/LVTTL  
FREQUENCY SYNTHESIZER  
ICS8402I  
General Description  
Features  
The ICS8402I is a general purpose,  
Two LVCMOS/LVTTL outputs  
S
IC  
Crystal-to-LVCMOS/LVTTL High Frequency  
Synthesizer and a member of the HiPerClockS™  
family of High Performance Clock Solutions from  
IDT. The ICS8402I has a selectable TEST_CLK or  
Selectable crystal oscillator interface or LVCMOS/LVTTL  
HiPerClockS™  
TEST_CLK  
Output frequency range: 15.625MHz to 350MHz  
Crystal input frequency range: 12MHz to 40MHz  
VCO range: 250MHz to 700MHz  
crystal inputs. The VCO operates at a frequency range of 250MHz  
to 700MHz. The VCO frequency is programmed in steps equal to  
the value of the input reference or crystal frequency. The VCO and  
output frequency can be programmed using the serial or parallel  
interfaces to the configuration logic. The low phase noise  
characteristics of the ICS8402I make it an ideal clock source for  
Gigabit Ethernet and SONET applications.  
Parallel or serial interface for programming counter and  
output dividers  
RMS period jitter: 30ps (maximum)  
Cycle-to-cycle jitter: 100ps (maximum)  
Full 3.3V or mixed 3.3V core/2.5V output supply  
-40°C to 85°C ambient operating temperature  
Available in both standard (RoHS 5) and lead-free (RoHS 6)  
packages
