Vayu/Jacinto6/DRA74x: Are there any special considerations for tuning of the SATA interface and PHY's?

tshelbur

I have a customer using a SATA DVD player with a Vayu/Jacinto6 (DRA74x) device. They have the interface working with their 19.2MHz oscillator using the standard SATA clock values from the TRM.

The question came up whether there were any special SATA PHY tuning requirements and if so what is the proper tuning process for the SATA interface on customer specific hardware.

Hi Thomas,
I would recommend to read first "SATA board design and layout guidelines" in the DRA75x/DRA74x Data Manual. If the board design matches the guidelines, no tuning will be required. The TRM settings must suffice to SATA run properly.
P.S. I think there was also TX PHY SCP settings in the TRM in addition to RX.

Regards,
Stan
