TPS23754: Reference design or EVM for PoE+ and 1000base-T solution

Part Number: TPS23754

Is there Reference design or EVM for PoE+ with 1000base-T solution?

I looked like existing PoE+ designs are 100base-T only.

(For example, TPS23754's EVM, etc)

If there matched design: PoE+ with 1000base-T the other than TPS23754, it is OK.

Hi Satoshi,

Please refer to TPS23754EVM-383: www.ti.com/.../TPS23754EVM-383
The connector "J3" can support: 10/100/1000 Base-T, Power over Ethernet+ (PoE+).

Data and power are independent in PoE, you could choose any PoE PD with a 1000base-T transformer.

Please kindly let me know if there's further questions, thanks!

Thank you for reply,

Sorry for additional question;
TPS23754EVM-383 is prepare many test points (User's manual page-4).
Is there test data or waveform for these test points?

Best regards,
Satoshi

Hi Satoshi,

For some waveform (ex: start-up), it can be found on datasheet.

For the test data, unfortunately, we don't have test data for all test points. We would recommend you order one EVM to test the points that you are interested in.

Thanks!
