APPROVED PRODUCT  
C9811x2  
Low EMI Clock Generator for Intel 810 Chipset Systems  
2-Wire SMBUS Control Interface  
The 2-wire control interface implements a write slave only interface according to SMBus specification. (See Fig. 7 / P. 8).  
Sub addressing is not supported, thus all preceding bytes must be sent in order to change one of the control bytes. The  
2-wire control interface allows each clock output to be individually enabled or disabled. 100 Kbits/second (standard  
mode) data transfer is supported.  
During normal data transfer, the SDATA signal only changes when the SDCLK signal is low, and is stable when SDCLK  
is high. There are two exceptions to this. A high to low transition on SDATA while SDCLK is high is used to indicate the  
start of a data transfer cycle. A low to high transition on SDATA while SDCLK is high indicates the end of a data transfer  
cycle. Data is always sent as complete 8-bit bytes, after which an acknowledge is generated. The first byte of a transfer  
cycle is an 8-bit address. W#=0 in write mode.  
The device will respond to writes to 10 bytes (max) of data to address D2 by generating the acknowledge (low) signal on  
the SDATA wire following reception of each byte. Data is transferred MSB first at a max rate of 100kbits/S. The device  
will not respond to any other control interface conditions, and previously set control registers are retained.
