Industry’s lowest latency highest ESD industrial Gigabit Ethernet PHYs

Introduced as the industry’s lowest latency and highest electrostatic discharge (ESD) industrial Gigabit Ethernet physical layers (PHYs), a new family of six devices has been unveiled by Texas Instruments (TI). The devices enable engineers to bring real-time industrial Internet of Things (IIoT) capabilities to rugged factory automation systems, motor drives, and test and measurement equipment. The new DP83867 family meets stringent electromagnetic interference (EMI) and electromagnetic compatibility (EMC) standards, reduces power consumption, and offers designers flexibility with multiple temperature, media access control (MAC) interface and packaging options. Key features : 1 - Industry’s lowest latency: Latency is less than 400 nanoseconds (ns) at 1,000 Mbps and 100 Mbps – 50 percent better than the competition. This reduces controller cycle times, improving real-time performance of standard IEEE 802.3 Ethernet connections in industrial systems. 2 - Industry’s highest ESD protection: ESD protection exceeds 8kV to surpass IEC 61000-4-2 standards, which is four times better than the competition. High ESD protection reduces the failure rate of Industry 4.0 systems by shielding against high-voltage faults. 3 - EMI mitigation: The DP83867 exceeds stringent standards for EMI/EMC from International Electrotechnical Commission (IEC), Comité International Spécial des Perturbations Radioélectriques (CISPR) and European Standards (EN). By exceeding the EN55011/CISPR11 Class B-level testing standards, the DP83867 gives designers more design headroom so that they can go to production faster. 4 - Power savings: Wake-on-local area network (LAN) (WoL) and power-down modes offer energy savings when the system is in a standby state. In addition, the DP83867 offers active power consumption of less than 460mW, which is at least 30 percent lower than the competition. 5 - Scalability across the temperature range: The DP83867 family offers options that allow designers to design across the full temperature range from -40C to 105C. This enables designers to adapt one design for multiple temperature environments, from commercial to extended industrial temperatures. Tools and support to speed design - Evaluation modules (EVMs) are available enabling designers to quickly and easily evaluate the new devices. The DP83867IRPAP-EVM supports the gigabit media independent interface (GMII) and reduced GMII (RGMII). The DP83867ERGZ-R-EVM supports RGMII. Designers can download IBIS models and the JTAG BSDL model to further speed evaluation. Designers can also jumpstart their design with the EMI/EMC-compliant industrial-temperature-grade Gigabit Ethernet reference design, which includes the Sitara AM335x processor with integrated Ethernet MAC and switch, says the company.
