S-ATA signals
AMD G-series SOC offers two S-ATA interfaces. One of them is always carried out on the golden card edge connector. The other interface is optional; it is
available only in case the module purchased doesn
’
t have an embedded SATA Flash Drive onboard.
The interfaces are SATA III, with support of 1.5Gbps, 3.0 Gbps and 6.0 Gbps data rates (the GX-210JA SOC supports only SATA II, therefore with that device the
maximum data rate supported is 3.0 Gbps)
Here following the signals related to SATA interface:
S/SATA0_TX-: Serial ATA Channel #0 Transmit differential pair
S/SATA0_RX-: Serial ATA Channel #0 Receive differential pair
S/SATA1_TX-: Serial ATA Channel #1 Transmit differential pair (optional, factory alternative to embedded SSD).
S/SATA1_RX-: Serial ATA Channel #1 Receive differential pair (optional, factory alternative to embedded SSD).
SATA_ACT#: Serial ATA Activity Led. Active low output signal at +3.3V_S voltage.
10nF AC series decoupling capacitors are placed on each line of SATA differential pairs.
On the carrier board, these signals can be carried out directly to the SATA connector.
