4.2.4 MediaLB Connector

Media Local Bus (MediaLB) is an on-PCB or inter-chip communications bus, specifically designed to standardize a common hardware interface and software API library. This standardization allows an application or multiple applications to access the MOST® (Media Oriented Systems Transport) Network data, or to communicate with other applications, with minimum effort.

On SAM V71 Xplained Ultra the MLB module of the ATSAMV71Q21 is connected to a MediaLB connector implemented with a 40 pin SAMTEC QSH-020-01-L-D-DP-A. This connector is intended to interface with a board that includes the MOST INIC and the MOST-50 physical layer connector (such as a Physical+ Interface Board OS81092 ePhy) or with other MOST tools. Table 4-13 shows all connections between the ATSAMV71Q21 and the connector.

Info: To use the MediaLB connector with an external kit that requires 12V, a 12V supply must be connected to the power jack.
