Features/Benefits:  
Programmable output frequency, divider ratios, output  
rise/falltime, output skew.  
48-Pin 300-mil SSOP and TSSOP  
Programmable spread percentage for EMI control.  
Watchdog timer technology to reset system  
if system malfunctions.  
* These inputs have a 120K pull up to VDD.  
** These inputs have a 120K pull down to GND.  
Programmable watch dog safe frequency.  
Support I2C Index read/write and block read/write  
operations.  
For PC133 SDRAM system use the ICS9179-06 as the  
memory buffer.  
For DDR SDRAM system use the ICS93705 or  
ICS93722 as the memory buffer.
