DP83TC811R-Q1: TIDA-010076 ref schematic

Part Number: DP83TC811R-Q1
Other Parts Discussed in Thread: TIDA-010076, DP83TC811

Dear team, 

The customer are trying to design single pare Ethernet with PoE for their application. so we promoted TIDA-010076.

At user guide of TIDA-010076, We can see below Block but it seems using short distance(1m cable?). The target distance of customer is over 100m up to 200m distance for industrial application. 

1. Is below concept available for long distance application? If not, Could you recommend ref schematic for long distance up to 200m?

2. For PoE, Do we need another device like PD and PSE?  

3. Is there any application for single pair Ethernet available PoE? How about DP83TD510? 

Thank you.

    Hi Dino,

    Can you provide more information about the end use application for design?

    The DP83TC811 has a maximum cable reach of 100m in reference design TIDA-010076. The DP83TD510 is a 10Mbps Ethernet PHY that can support PoE and 200+ m cable reach. Will this data rate be suitable for the application proposed?

    Regards,
    Justin

    Hello Justin, 

    Thank you for your comment. 

    The most important thing of this application is maximum cable reach and cost. The DP83TD510 is more suitable for the customer application. 

    Is there any application note or reference design for DP83TD510 with PoE? Regarding DP83TD510(Single Pair Ethernet) with PoE application, Do we need external PD or PSE for PoE? 

    Thank you.

    Hi Dino,

    The DP83TD510 will have a reference design supporting PoE with the external power regulation components. I've reached out directly to share with you.
