DP83869HM: LLPT in 1000M Media Convertor Mode

Philipp Schneider1

Part Number: DP83869HM

Hello,

we are using the DP83869HM in converter mode with the MSP0430FR2111IRLL. According to the datsheet it is possible to enable or disable LLPT via boot strapping in 100M media convertor mode but not in 1000M media convertor mode. But if we configure the DP83869HM in 1000M media convertor LLPT is enabled.

Is the LLPT function by default activated in 1000M media convertor mode and cannot be disabled?

Regards,

Philipp

Hi Phillip,

Link Loss Pass Through should function the same for 100M and 1000M operation, including strap operation. This is a typo in the datasheet that will be corrected in the next revision. Please let me know if you have any further questions.

Thank you,

Nikhil
