133 MHz I2C Clock Generator for mobile Pentium®III / Rambus Systems  
Preliminary  
Frequency Extension  
Frequency Extension is a feature in this device that allows the user to expand on the clock frequency originally selected  
following table 1, page1.  
This feature provides the user two additional selection lines FS1 and FS0 that are used to select the desired percentage  
of frequency extension.  
These signals are bi-directional strapping pins and are latched into the device at power up, as described on page 3.  
This feature does not effect the frequency of the 48MHz and REF(0:2) clocks, therefore, 48MHz and REF(0:2)  
frequencies remain the same regardless of the status of FE(0:1) and Sel133/100#.  
For default frequencies (100MHz or 133.3MHz) these signals should be connect high through a 10Kresistor.  
When the frequency extension is applied Spread Spectrum is not applicable.

Maximum Ratings  
This device contains circuitry to protect the inputs  
against damage due to high static voltages or electric  
field; however, precautions should be taken to avoid  
application of any voltage higher than the maximum  
rated voltages to this circuit. For proper operation, Vin  
and Vout should be constrained to the range:  
Maximum Input Voltage Relative to VSS: VSS - 0.3V  
Maximum Input Voltage Relative to VDD: VDD + 0.3V  
Storage Temperature:  
Operating Temperature:  
Maximum ESD protection  
Maximum Power Supply:  
-65ºC to + 150ºC  
0ºC to +85ºC  
2000V  
5.5V  
VSS<(Vin or Vout)<VDD  
Unused inputs must always be tied to an appropriate  
logic voltage level (either VSS or VDD).
