eSATA with i.MX6

Can someone please explain what precisely is meant by eSATA (external analog logic also needs to support eSATA). I took this from IMX6DQRMr2 page 4491 regarding the SATA interface. By external logic, is the HDD that will be connected to iMX6 meant? If I buy a commercial HDD with eSATA interface, is it enough to make it work? Besides, isnt eSATA just SATA data connection? What analog logic difference is there such that mentioning such a phrase for eSATA is required whereas its not for SATA?


I already know that the shielding etc. is different between eSATA and SATA and so are the port physical architecture, but what changes when it comes to the signal transmitted?


Thanks in advance,
