This is probably a long shot but I'm wondering if serial ATA can be run at a speed less than 1.5 Gbps? I have a V4 fpga but no MGTs so it would be nice if I could make it work with regular chipsync resources which can only go about 800 mbps.
Thanks, Clark
No. All of the SATA hard drives have an on board clock source that transmits and receives at 1.5 Gbps.

Use National serdes to handle the serial stream. A lot cheaper than a v5.
The National SERDES does out of band signaling? Handles spread spectrum? You're talking about a SATA PHY? What's the part number?
Or were you thinking "serdes" generically?
