TIDP83867IRPAPRG4
Overview
The DP83867IRPAPRG4 is a robust, low-power Gigabit Ethernet Physical Layer (PHY) transceiver designed for industrial applications. It supports 10BASE-Te, 100BASE-TX, and 1000BASE-T protocols while offering extremely low latency through RGMII, GMII, and MII interfaces. This device is specifically engineered for high EMC performance, exceeding 8kV IEC 61000-4-2 ESD protection standards and meeting EN55011 class B emission limits.
Why Choose This Part
The transceiver offers ultra-low RGMII latency (TX < 90ns, RX < 290ns) and 16 programmable delay modes to simplify timing closure. It features integrated MDI termination resistors and programmable impedance to reduce external component count and PCB complexity. Its industrial design includes cable diagnostics and a fast link drop mode for mission-critical connectivity.
Applications
Key Specifications
Getting Started
Designers can evaluate the chip using the DP83867ERGZ-S-EVM or DP83867EVM-PDK evaluation modules from Texas Instruments. Configuration is typically performed via the MDIO/MDC management interface, and TI provides the SNLA246 application report to guide RGMII layout and timing optimization. Ensure the thermal pad on the 64-HTQFP package is properly soldered to a ground plane for heat dissipation and EMC performance.
