Protocol analyzer for consumer electronics |
摘要 |
A protocol analyzer for analyzing traffic on a bus. A tap card is used to tap into a bidirectional bus. The tap provides a pass through connection from the card to the host and taps off of the bus. While tapping off the bus, stubs lengths are minimized and input capacitance is minimized. A repeater that preferably has no internal termination provides a differential input and a differential output. The bus lines are input to one of the inputs in the differential inputs and a reference voltage is provided to the other differential input. The reference voltage enables the tap to determine if the data is high or low. A jumper is also included in the tap such that the reference voltage can be selected from the host or from the pod. |
