Interpreting manufacturers’ datasheets

datasheetsWe’ve all heard the phrase that timing is everything. Nowadays, the buses that connect, for example, processors to main memory require very precise timing, in the order of tenths of nanoseconds. Manufacturers provide all this information in their datasheets, but it needs to be combined with the appropriate Input/output Buffer Information Specification (IBIS) models and PCB (printed circuit board) construction characteristics, such as trace impedances, their length, number of loads and their distribution, etc.

When there are multiple users or stations sharing the same communication medium or channel, access control is required to avoid two or more stations transmitting at the same time, which can cause interference and even make the communication impossible.
