Serial ATA (SATA)
The EP80579 has an integrated SATA host controller that supports independent DMA
operation on two ports and supports data transfer rates of up to 3.0 Gb/s (300 MB/s).
This technology consists of a receiver and transmitter.
The EP80579 SATA ports support Gen1 Electrical Specifications for “Short” Backplane
and External Desktop Applications running at 1.5Gbp/s. These are defined on page 12
of the Serial ATA II: Electrical Specification Revision 1.0 26-May 2004. The EP80579
silicon and platform supports SATA hot plug. Use of an interlock switch is optional.
While SATA controllers commonly provide hot plug functionality, SATA cable assemblies
are not standardized, especially the SATA power cable. To support SATA hot plug, any
EP80579 platform needs to support a SATA 15-pin power connector interface with a hot
plug compatible SATA HDD.
The EP80579 supports the Serial ATA Specification, Revision 1.0a. The EP80579 also
supports several optional sections of the Serial ATA II: Extensions to Serial ATA 1.0
Specification, Revision 1.0 (AHCI support is required for some elements).
This section describes the electrical characteristics of the SATA interface.

SATA Vdiff, tx (VIMAX/MIN10) is measured at the SATA connector on the transmit side
(generally, the motherboard connector), where SATA mVdiff p-p = |SATA[x]TXP/RXP -
SATA[x]TXN/RXN|
