Hi Team,
My customer is considering implement 10Base-T1L to their product, they have following questions about 10Base-T1L and DP83TD510E. Please kindly help these. Thanks.
Besides following questions, customer is asking if we can hold a seminar to teach them how to start use DP83TD510E. For example, how should they construct the circuit to use it.
Is it possible? We can discuss via mail for detail.
1. I think DP83TD510E don't have integrated MAC, do TI have other parts with or without integrated MAC(or on roadmap) for 10Base-T1L besides DP83TD510E?
2. I think 10Base-T1L supports point to point connection, can it connect multiple PHY by daisy-chain connection? Please show us if there's any example.
3. Is there designated or recommended connector to use for 10Base-T1L?
4. Is there any designation or example of PCB pattern design for TX+,TX-,RX+,RX- for 10Base-T1L?
5. Is there any power IC recommendation for DP83TD510E?
6. Is it not necessary to add something, for example varistor, to suppress noise on communication line? Please let me know if there's any recommendation for noise suppress implementation.
7. What is the definition of "short reach" in DP83TD510E datasheet? Less than 200m?
8. I think 10Base-T1L supports PoDL, can DP83TD510E support supplying and receiving power? Please show us if there's any reference design.
9. For SPE, I think normally capacitor is used for isolation instead of transformer, how can we superimpose power to transmit/receive data line? Is there any example schematic?
Thanks.
Regards,
Jo
