PEX8505-AA25BI G

The PEX8505-AA25BI G is an active copper transceiver that provides a physical interface between 10 Gigabit networks and electrical-optical channels. This field and working principle can be divided into a few key areas:

Physical Interface

The PEX8505-AA25BI G provides a physically robust interface with a wide variety of switches, routers and other devices in a 10Gigabit network. It is designed to meet the IEEE 802.3u and 802.3ae Ethernet standard and provides low latency and high data rate performance. The active copper transceiver uses a four-port design that supports a duplex data rate of 25G/s and a continuous signaling rate of 40Mbps. This physical interface supports both full-duplex and half-duplex data transmission.

Circuit Design

The PEX8505-AA25BI G utilizes an integrated balanced single-ended architecture, which consists of four independent receivers and four independent drivers. This architecture eliminates the need for additional external components, reduces circuit complexity and increases design flexibility. The low noise level created by the single-ended architecture helps the transceiver to achieve its high speed data rate.

Signal Routing

The transceiver is equipped with several built-in signal routing features, including automatic polarity detection and port level control. The automatic polarity detection ensures that each port transmits at the correct data rate and is properly connected to the intended destination. The port level control feature provides an extra layer of control for specific ports, allowing for the port to either be enabled or disabled as needed. These routing features help to minimize network disruptions and increase transmission performance.

Powering the Device

The transceiver has an integrated power supply and is powered by a single +5v DC power supply. This power supply is provided by an on-board voltage regulator which helps to ensure a stable and reliable power source. The voltage and current requirements of the device are specified in the device’s datasheet. The device also supports Power Over Ethernet (PoE) and is compatible with a range of PoE devices.

Error Detection and Correction

The PEX8505-AA25BI G utilizes several error detection and correction techniques. It includes a 16-bit error detection and correction scheme as well as several built-in diagnostic modes which help to identify and correct any problems with the transceiver. Additionally, the device supports a range of error reporting methods which can be used to monitor the performance of the transceiver.

Conclusion

The PEX8505-AA25BI G is an active copper transceiver that provides a physically robust interface with a wide variety of switches, routers and other devices in a 10Gigabit network. It utilizes an integrated balanced single-ended architecture, incorporates several built-in signal routing features, is powered by a single +5v DC power supply, and includes several error detection and correction techniques. This device is ideal for high speed data transmissions and is suitable for a range of 10Gigabit network applications.
