USB Connector Recommendations

Proper connector choice is critical to ensure adequate USB signal quality. For the Intel
Quark™ SoC X1000 the initial recommendation is the use of single USB connectors,
empirical data has shown that quad-stack USB connectors may add interference
causing poor USB signal quality. Refer to usb.org for a list of tested connectors.
5.3.2.1

External Connector Recommendations

The cable and PCB mating connector must pass the TDR requirements listed in the USB
2.0 Specification
5.3.2.1.1 USB 2.0 Internal Connector
It is possible to define the internal connector pin list based on individual needs.
However, an example connector pin list for 2-port internal cable connection supporting
USB 2.0 is shown below.
