ADP065 User’s Manual
SATA1 & SATA2: SATA Connectors
Two SATA connectors are available on the ADP065. With the ADP065 stacked above the CPU, SATA2 breaks out the higher order port, and
connector SATA1 breaks out the lower order port. Both connectors permit connectivity with latching or non-latching SATA cables.

Bottom: PCIe Connector
The PCIe connector is the connection to the system CPU. The position and pin assignments are compliant with the
PCIe/104 Specification
.
(See PC/104 Specifications on page 14)

Selecting the Stack Order for the ADP065
The following is a list of rules to determine where the ADP065 falls within the stacking order of the system. These rules may be overridden by
the devices hosting the USB 3.0 and SATA connections.
1.
If a SATA link is used (with no USB 3.0 link), the ADP065 must be placed within six boards of the CPU.
2.
If a USB 3.0 link is used, the ADP065 must be within four boards of the CPU.
