• Home Networking
• Industrial Automation
• Connected Vehicle Solutions
• Internet of Things (IOT) Device Connectivity
• Industrial Ethernet

The DP83867IRPAPR is an excellent choice for power sensitive applications, as well as for applications that require high reliability and robust connectivity for communication between different devices. It has been designed specifically to provide excellent connectivity and low power consumption.

Working Principle of DP83867IRPAPR

The DP83867IRPAPR is a full duplex physical layer interface designed to support speeds up to 1 Gigabit per second (1Gbps). It supports half-duplex systems that are compatible with 10Mb/s, 100Mb/s, and 1000Mb/s Ethernet. It is a low power, low latency, cost-effective solution that meets IEEE 802.3 standards.

The device is divided into five main sub-blocks, which are the MII/RMII port, the 1000Base-T/100Base-TX transceiver, the Extended PHY Communications protocol (XPCS) transceiver, the mac-level clock recovery unit and the integrated synchronous Ethernet MAC. The MII/RMII port interfaces with the MAC and enables, MAC-level protocol communication for all Ethernet speeds. The 1000Base-T/100Base-TX transceiver supports all speed specific to Fast Ethernet and Gigabit Ethernet, while optional MII and RGMII can be used with lower speeds. The XPCS transceiver supports data transmission using a serial interface that can be configured to support both XAUI and 1000Base-X standards.

The integrated synchronous Ethernet MAC supports IEEE 802.3 and is optimized to support higher speeds. The integrated MAC can also support a very low power sleep state that allows the DP83867IRPAPR to be a power efficient solution. The clock recovery unit ensures data integrity and accurate timing on the link.

The DP83867IRPAPR also supports advanced power management features. To reduce current consumption, the device features a low standby current, timeouts and autonomous power shutdown. Additionally, the device supports Wake-On-Lan and Magic Packet detection. These features allow the device to enter a low power state when not in use, conserve energy and reduce cost for applications that need to be constantly connected.

Overall, the DP83867IRPAPR is a versatile and cost-effective solution for high-speed Ethernet connectivity. It offers robust, reliable, and power-efficient connectivity for a broad range of applications.
