Part Number: TIDA-010046 Other Parts Discussed in Thread: TPS23730 , TPS2372 , TPS2373 Hi Team,
My customer is interested in this reference design, however, they would like to implement >25W PD, do we have recommended alternative part for PD controller…
Part Number: TIDA-010046 Other Parts Discussed in Thread: TPS23754 , Hi,
I am in the proces of designing a PoE+ PD device using a DP83848 and a TPS23754. I have the develoments boards for both these ICs.
I don't want to use a more expensive 4-pair magnetics…
Part Number: TPS23861 Other Parts Discussed in Thread: TIDA-010046 Hi team,
Could you please answer below questions?
1. Is it ok to change SEN1 resistor 22.1 ohm to 22ohm?
2. Is it ok to connect RJ45 and Xfmr as below?
3. Basically, PD device has two…
Part Number: TIDA-010046 Hi, in this reference design GND and EARTH is coupled with a 1M and a 4700 pF capacitor near the magnetic. Could you please explain the reason why? The documentation says: 'Additional capacitors are required to interconnect chassis…
Part Number: DP83825I Other Parts Discussed in Thread: TIDA-010046 , DP83825 In our PD PoE design we are using the DP83825I as PHY. After extensive tests we have found that the link is more reliable leaving the PHY facing tap center of the transformers…
Part Number: DP83825I Other Parts Discussed in Thread: TIDA-010046 , DP83822I If I connect two devices in a repeater configuration, can I simply have one set for master (with local 25MHz xtal connected) then feed the master's 50MHz clock signal to the…
Hi Phil,
I don't believe that Wireshark will work in this scenario. I am proposing to use either a packet generator software such as iperf, or use a third EVM to generate and check packets via MDI. Do you have a third board that can work in this scenario…
Part Number: TPS23861 Other Parts Discussed in Thread: TIDA-010046 Hello.
I designed a PSE circuit using TPS23861 and KSZ8041 Even if you connect to a hub (that is not PD), it will not link up. For the connection between the transformer and the connector…
Part Number: DP83825I Other Parts Discussed in Thread: TIDA-010046 , DP83825 , Hi,
how to connect the two DP83825 in repeater mode? in the datasheet, master's TX is connect to RX, while in the TI design TIDA-010046, TX is connect to the TX of slave. …
Hi Paul,
Thank you for your question. What type of design tools specifically are you and the customer looking for?
