SATA Connector
The Apollo Lake family of SoCs embeds a SATA Controller, which offers two SATA III, 6.0 Gbps interfaces.
Of these interfaces, one SATA channel is carried out to a standard male S-ATA connector, CN11 (the other SATA channel is
available on the M.2 Key B socket, CN14, please check par. 3.3.7)
Here following the signals related to SATA interface:
S/SATA1_TX-: Serial ATA Channel #1 Transmit differential pair
S/SATA1_RX-: Serial ATA Channel #1 Receive differential pair
10nF AC series decoupling capacitors are placed on each line of SATA differential pairs.
A dedicated power connector, CN10, can be used to give supply to external Hard Disks (or Solid State
Disks) connected to the SATA male connector.
The dedicated power connector is a 4-pin male connector, type HR p/n A2001WV-S-04 or equivalent,
with pinout shown in the table on the left.
Mating connector: HR A2001H-04P housing with HR A2001 series crimp terminals.
