ZHCS034C January 2011 – August 2018 TCA4311A
PRODUCTION DATA.
The TCA4311A was designed for applications in which a portion of a communication bus contained on an I/O card or add-on card, is inserted into a live backplane where the main communication bus is already active, which is known as hot-swapping. The two types of communication buses supported by the TCA4311A are I2C and SMBus. System management for PCI cards is an application of the SMBus protocol, which adds on to the electrical specifications and hardware addressing protocol of I2C with second-level software for building special systems that may include dynamic addressing. The following application schematics and descriptions give examples of a typical application of the TCA4311A (Figure 9), a CompactPCI™ system configuration (Figure 12), a PCI system configuration (Figure 13), repeater or bus-extender application (Figure 14), and a system with disparate voltage supplies (Figure 15).
