TPS23753AEVM-001

The TPS23753AEVM-001 board is an evaluation and demonstration board and kit from Texas Instruments. The board is designed as a power-over-ethernet (PoE) technology reference design platform and is built to evaluate the features and performance of TI’s TPS23753 PoE Powered Device (PD) controller. By utilizing the TPS23753AEVM-001 board, applications such as single-port PoE intermediate-power PSE, multiple-port PoE mid power and long-reach PSE, as well as mid power ports with IEEE 802.3af inline power detection can all be evaluated.

The TPS23753AEVM-001 board consists of the TPS23753AEVM-001 and the TPS23753AEVM-002 modules. The TPS23753AEVM-001 module is a PoE powered device controller evaluation module (EVM). The board provides an isolated power interface that provides separate inputs for data and power transmitters. It also has two separate output ports, one to provide the main load adapter, and the other to service the TPS23753AEVM-002 dual port controller. The TPS23753AEVM-002 module is a circuit board that provides a secondary (extended) channel for connecting to an isolated load.

The application field of TPS23753AEVM-001 board mainly includes the technology of PoE (Power over Ethernet). By employing PoE technology into electronic devices like IP cameras, WLAN Access Points, or others, it can greatly reduce the number of cables used in an installation and simplify network wiring requirements. In addition, the board supports other applications such as single-port PoE powered device (PD) or multiple-port Ethernet PoE mid-power or long-reach Power Sampling Equipment (PSE) with or without IEEE 802.3af inline power.

The TPS23753AEVM-001 board is built on TI’s TPS23753 PoE Powered Device Controller. The TPS23753 is a IEEE 802.3af compliant Powered Device (PD) controller with integrated Power Source Equipment (PSE) power detection. The TPS23753 features a variety of port protection features, including overload current protection, over-temperature disconnect, and ESD protection. It also allows for software control of the power delivery system, by integrating a PD-side master and slave enable pins.

The TPS23753AEVM-001 board also implements various power source equipment (PSE)/powered device (PD) interface protocols to enable the connection between the PSE and the PD. These include the standard IEEE 802.3af protocol, as well as several proprietary protocols. The board is capable of negotiating with the power source and the PD devices over all of the protocols provided, and can identify the PD or PSE device at power up.

The TPS23753AEVM-001 board utilizes Power over Ethernet (PoE) technology to supply DC power over an Ethernet twisted pair cable. The board is designed to evaluate the features and performance of TI’s TPS23753 PoE Powered Device (PD) controller for single-port PoE intermediate-power PSE, multiple-port PoE mid power and long-reach PSE, as well as mid power ports with IEEE 802.3af inline power detection. It is also designed to provide an isolated power interface which provides separate inputs for data and power transmitters, and has two separate output ports providing either the main load adapter or the TPS23753AEVM-002 dual port controller.

The TPS23753AEVM-001 board and TPS23753AEVM-002 modules provides a reliable, cost-effective platform for evaluating the features and performance of the TI’s TPS23753 PoE powered controller. In addition, the board supports various power source equipment/powered device interface protocols, allowing for the easy connection of the PSE and PD devices, and allowing for monitoring and control of the power delivery system.

The board also provides an ideal platform for application designers to explore greater flexibility in PoE applications, allowing for simplification of design, reduced cost of material, and a more reliable performance.
