AM5728: PHY Delay Compensation for AM57xx IDK

Hello,

In chapter 4.3.5.1.3. PHY Delay Compensation for AM57xx IDK:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/05_03_00_07/linux/Industrial_Protocols_PTP.html#phy-delay-compensation-for-am57xx-idk

"Furthermore, the PRU-ICSS PHY TLK110 on AM57xx IDK introduces a latency of 86 ns in the TX and 186 ns in the RX direction."

I have searched TLK110 datasheet but I can not find those timings.

Transmit packet latency = 4.8 * 10 = 48ns

Receive packet latency = 19 * 10 = 190 ns

Could you please tell me where to get these times from?

Best regards,

Gonzalo
