The PEX8605-AB RDK is a robust, cost-effective and low power loss multiplexer and demultiplexer that performs two switchings of i2C lines for multiple systems. It also supports an I2C fan out port that enables up to four systems to use the same I2C bus. This switch can be used standalone, or connected to a master IC that controls the operation of the multiplexer and which can provide diagnostics and control of multiple I2C bus operations. This device is ideal for applications where multiple systems requiring different I2C buses for data reading and writing are connected to the same signal bus.

The PEX8605-AB RDK can be used in a variety of applications, from Power over Ethernet (PoE) applications to consumer electronics. It can also be used in industrial automation and robotics applications to allow multiple systems to share the same I2C bus without worrying about signal interference or packet loss. The device is compact and can be embedded on a number of systems, making it an ideal choice for system and device integration applications.

The PEX8605-AB RDK features a Data and Control line switch and a bidirectional 8-bit Data Multiplexer/Switch, which allow for easy multiplexing and demultiplexing of two switchable I2C lines when applicable. When enabled, the Data and Control line switch transmits the set of I2C commands and data bytes to the Data Multiplexer/Switch, which then transmits the same set of commands and data bytes to the fan out port. On the other hand, the Data and Control line switch also enables the transmission of fan out data bytes from the Data and Control line switch to the Data Multiplexer/Switch.

In addition, the Data Multiplexer/Switch supporting low voltage differential signaling (LVD) allows data to be sent and received between the master and the devices connected to the fan out port at high Bit Error Rates (BER). This improves signal integrity and can provide an additional layer of reliability for any critical I2C operations. The data multiplexing can be controlled either by the commands written in the Data and Control line switch registers or by externally configured registers.

The PEX8605-AB RDK is a high-density, energy-efficient I2C multiplexer/demultiplexer that can be used to save cost, board space and power loss. Its multiplexing and demultiplexing capabilities, as well as its support for LVD, make it a versatile device for a variety of applications. In addition, the device\'s internal hardware control logic makes it easy to configure the device\'s settings in various ways, allowing for efficient and efficient multiplexing operations.
