Pegelumsetzende, hot-swap-fähige I2C- und SMBus-Buffer für verbessertes Busverhalten

(PresseBox) (Milpitas, )
Linear Technology Corporation erweitert seine I2C- und SMBus-Bus-Buffer- und Rise-Time-Accelerator-Familie um die beiden neuen Produkte LTC4308 und LTC4309. Mit zunehmender Anzahl von Steckkarten werden auch die kapazitiven Lasten auf dem Bus immer größer. Dadurch kann es zu einer kritischen Verlängerung der Signalanstiegszeiten kommen. Dieses Problem lässt sich zwar entschärfen, indem man den Bus mithilfe von Bus-Buffern in mehrere Teile aufteilt, doch wenn die Buffer-Offsets zu groß sind, werden u. U. die "Low"-Pegel-Spezifi-kationen verletzt. Der LTC4308 ist optimiert für Pegelumsetzung bis hinab zu 1V und produziert eine negative Offsetspannung für Busse mit sehr niederpegeliger Pull-up-Betriebs-spannungsversorgung; der LTC4309 hingegen bietet eine niedrige Dsitkcgojbbhoy, enp Tbkwde-Smfu, yienv Lspkenmnig-Ymiwhnxbxyavu cjd uqwgm Cuveykrrqqn-Fcbqdpu-Gtawogauadtve.
