PRELIMINARY  
ICS8427-02  
Integrated  
Circuit  
Systems, Inc.  
700MHZ, LOW JITTER  
LVCMOS/CRYSTAL-TO-LVHSTL FREQUENCY SYNTHESIZER  
GENERAL DESCRIPTION  
FEATURES  
The ICS8427-02 is a general purpose, six 6 differential LVHSTL outputs  
ICS  
LVHSTL output high frequency synthesizer and  
Selectable crystal input interface orTEST_CLK input  
HiPerClockS™  
a member of the HiPerClockS™ family of High  
Performance Clock Solutions from ICS. The  
ICS8427-02 can support a very wide output fre-  
TEST_CLK accepts the following input types:  
LVCMOS, LVTTL  
quency range of 15.625MHz to 700MHz.The device powers  
up at a default output frequency of 200MHz with a 16.66MHz  
crystal interface, and the frequency can then be changed  
using the serial programming interface to change the M feed-  
back divider and N output divider. Frequency steps as small  
as 125KHz can be achieved using a 16.66MHz crystal and  
the output divider set for ÷16. The low jitter and frequency  
range of the ICS8427-02 make it an ideal clock generator for  
most clock tree applications.  
Output frequency range: 15.625MHz to 700MHz  
VCO range: 250MHz to 700MHz  
Serial interface for programming feedback and output dividers  
Supports SSC, -0.5% downspread.Can be enabled through  
use of the serial programming interface.  
Output skew: 60ps (typical)  
Cycle-to-cycle jitter: 30ps (typical)  
2.5V core/1.8V output supply voltage  
0°C to 70°C ambient operating temperature  
Industrial temperature information available upon request
