Based on TI, DPHY440 supports up to 5dB at 750MHz and 2.5dB DE on its TX. Can I understand that retimer RX can compensate 5dB channel loss and retimer TX can compensate 2.5dB channel loss (processor EQ not included)?

Thanks

Your understanding on the RX EQ and TX DE is correct.

Retimer RX can compensate 5dB channel loss at 750MHz Nyquist frequency.

Hi,

The TX Pre-emphasis can provide 0dB or 2.5dB compensation.

The breakout board looks like this: suddendocs.samtec.com/.../hdr-128291-xx.pdf

You will have to contact Samtec for ordering information.

Thanks

David
