The Mictors are placed at the end of a stub that must be as short as possible, and are then daisy-chained off either end of the bus. When there is not enough room to place the Mictors at least 0.5 from the target, an alternate method can be used. This alternate method is to place the logic analyzer termination circuitry on the target and then extend the etch from the end of the termination circuitry over to the Mictor connectors. The connection from the Mictors to the logic analyzer must then be made with the E5351A. The E5346A contains the logic analyzer termination circuitry, and the E5351A does not Logic Analyzer PodTHIS PAGE INTENTIONALLY LEFT BLANK Debug Connectors and Logic Analyzer ConnectivityIntel 31154 133 MHz PCI Bridge Design Guide Design Guide Maximum Power Thermal SolutionsThermal Solutions Table 29.
