If the customer needs really fast data rates, then the parts on this slide are the parts for them. With data rates of 40Mbps to 100Mbps, these devices can handle the fastest of applications. The ISL3159 has been designed particularly for Profibus applications in factory automation where dedicated bus transceivers must provide: high differential output voltage of VOD ≥ 2.1V; data rate of up to 40Mbps; differential input capacitance of CIN ≤ 10pF; and fractional unit load of nUL = 1/5 (or 160 transceivers per bus segment). With 3.3V and 5V supply versions and many of the enhanced features that were covered earlier, the user is assured of finding a fit for a need for speed. Note that Renesas has added an even smaller package option, a 3mm x 3mm DFN that is another 45% smaller than the MSOP. One of the more interesting applications for such small packages are shaft encoders in motor controls where stringent space-saving requirements aim for very small form factor designs.
