ICS91309I  
Integrated  
Circuit  
Systems,Inc.  
High Performance Communication Buffer  
General Description  
Features  
The ICS91309I is a high performance, low skew, low jitter  
zero delay buffer. It uses a phase lock loop (PLL)  
technologytoalign, inbothphaseandfrequency, theREF  
input with the CLKOUT signal. It is designed to distribute  
high speed clocks in communication systems operating  
at speeds from 10 to 133 MHz.  
Zero input - output delay  
Frequency range 10 - 133 MHz (3.3V)  
5V tolerant input REF  
High loop filter bandwidth ideal for Spread Spectrum  
applications.  
Less than 125 ps cycle to cycle Jitter  
Skew controlled outputs  
Available in 16 pin, 150 mil SSOP, SOIC & 4.40mm  
TSSOP packages  
The ICS91309I provides synchronization between the  
input and output. The synchronization is established via  
CLKOUTfeedbacktotheinputofthePLL. Sincetheskew  
between the input and output is less than +/- 350 pS, the  
part acts as a zero delay buffer.  
Skew:Group-to-Group:<215ps  
Skew within Group: <100 ps  
Industrial temperature range: -40°C to +85°C  
ICS91309I has two banks of four outputs controlled by  
two address lines. Depending on the selected address  
line, bank B or both banks can be put in a tri-state mode.  
In this mode, the PLL is still running and only the output  
buffers are put in a high impedance mode. The test mode  
shuts off the PLL and connects the input directly to the  
output buffers (see table below for functionality).
