Intel
®
NM10 Express chipset 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 Disk onboard.
The interfaces are SATA II, with support of 1.5Gbps and 3.0 Gbps data rates
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.
