Overview

The DP83867ERGZT is a high-performance, robust Gigabit Ethernet Physical Layer (PHY) transceiver supporting 10/100/1000 Mbps speeds. It features flexible MAC interface options including RGMII and SGMII, and is designed to exceed rigorous industrial EMC requirements with 8kV ESD protection. This PHY is particularly notable for its extremely low latency, which is critical for time-sensitive networking and real-time industrial applications.

Why Choose This Part

The component offers industry-leading latency with TX less than 90ns and RX less than 290ns, supporting deterministic communication. It simplifies PCB design with integrated MDI termination resistors and programmable RGMII delay modes, while its wide operating temperature range of -40C to 105C ensures reliability in harsh environments.

Applications

Industrial Ethernet (TSN)
Utilizes Time Sensitive Networking compliance and low latency for deterministic control loops in factory automation.
EtherCAT and Profinet Nodes
Provides the physical interface for high-speed industrial fieldbus protocols requiring precise timing and high EMC resilience.
Wired Wireless Backhaul
Serves as a reliable RGMII/SGMII bridge for wireless access points and small cell base stations.
Test and Measurement
Integrates cable diagnostics and Start of Frame Detect for IEEE 1588 hardware time-stamping in precision instruments.
