SATA connectors
The AMD Ryzen Embedded V1000 family of Processors embed 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, CN14 (the
other SATA channel is available on the M.2 Key B socket, CN18, 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, CN15, 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.
Maximum allowed power consumption for this connector is 1A.
