A dedicated power connector, CN 15, can be used to give supply to external Hard Disks (or Solid State
Disks) connected to one of the two SATA male connectors.
The dedicated power connector is a 4-pin male connector, type MOLEX p/n 89400-0420 or equivalent,
with pinout shown in the table on the left.
Mating connector: MOLEX 87369-0400 crimp housing with MOLEX 50212 crimp terminals.
An adapter cable for powering SATA disks from this connector is also contained inside the dedicated
cable kit (CABKIT992) for SBC-992-pITX board. Please also check chapter 5.2.1for further details.
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
S/SATA1_RX-: Serial ATA Channel #1 Receive differential pair
10nF AC series decoupling capacitors are placed on each line of SATA differential pairs.

SD + miniSIM combo card slot
AMD G-Series SOC embeds a SD 3.0 compliant Host controller, supporting SDxc UHS-1
cards (speed transfer up to 104 MB/S with 4.bit SD cards). For this reason, on SBC-992-
pITX board there is also a socket, for the use of standard microSD cards, which can be used
as Mass Storage and/or Boot Devices.
Moreover, SBC-992-pITX board is designed to accept also miniSIM
cards, for use of miniPCI Express modems. These cards can be
inserted in the dedicated slot of connector CN10, which is a combo
μ
SD/MMC + miniSIM connector, push-push type, 2.7 mm global
height, type AVX p/n 009162006501150 or equivalent. Pinout here
reported is related only to signal routing on specific connector; internally
the pin-out is the same of any standard SD 3.0 and SIM card.
For ESD protection, on all signal lines are placed clamping diodes for voltage transient
suppression.
