Datasheet

The FSB signals have been combined into groups by buffer type in the following 

sections. In this document, the term “AGTL+ Input” refers to the AGTL+ input group as 

well as the AGTL+ I/O group when receiving. Similarly, “AGTL+ Output” refers to the 

AGTL+ output group as well as the AGTL+ I/O group when driving. 

With the implementation of a source-synchronous data bus, two sets of timing 

parameters are specified. One set is for common clock signals, which are dependent 

upon the rising edge of BCLK0 (ADS#, HIT#, HITM#, etc.), and the second set is for 

the source-synchronous signals which are relative to their respective strobe lines (data 

and address) as well as the rising edge of BCLK0. Asychronous signals are still present 

(A20M#, IGNNE#, etc.) and can become active at any time during the clock cycle. 

 identifies which signals are common clock, source synchronous, and 

asynchronous.
