DP83822HRHBR – TEXAS INSTRUMENTS

The Texas Instruments DP83822HRHBR is a high-speed, low-power, 10/100/1000BASE-T Gigabit Ethernet physical layer transceiver in a 48-pin LQFP package. It operates over a 3.135V to 3.465V supply voltage range and features integrated magnetics, simplifying board design. This device supports auto-negotiation and auto-MDI/MDIX, eliminating the need for external components for these functions. The DP83822HRHBR boasts a robust error correction mechanism, ensuring reliable data transmission even in challenging electromagnetic environments. Its low power consumption, typically under 1W during operation, is a key advantage in power-sensitive applications. Common use cases include industrial automation, networking equipment, and embedded systems requiring high-speed Ethernet connectivity. Its integrated features significantly reduce the bill of materials (BOM) cost and board space compared to discrete solutions. The device’s compliance with IEEE 802.3ab and 802.3 standards ensures interoperability with existing Ethernet infrastructure. Designers should consider the DP83822HRHBR when a compact, low-power, and cost-effective Gigabit Ethernet solution is required, particularly in applications demanding high reliability and ease of integration.
