The N-series Intel Pentium / Celeron
III, 6.0 Gbps interfaces.
Of these interfaces, one SATA channel is carried out to a standard male S-ATA connector, CN18 (the
other SATA channel is available on the M.2 Key B socket, CN20, please check par. 3.3.9).
Here following the signals related to SATA interface:
SATA1_TX+/SATA1_TX-: Serial ATA Channel #1 Transmit differential pair
SATA1_RX+/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, CN21, can be used to give supply to external Hard Drives (or Solid State
Drives) connected to the SATA male connector.
The dedicated power connector is a 4-pin male connector, type JST p/n S4B-PH-SM4-TB or
equivalent, with pinout shown in the table on the left.
Mating connector: JST PHR-4 crimp housing with JST SPH-002T-P0.5L crimp terminals.
