This application note describes the STMAV340 evaluation board design and features, as well as the PCB layout.
This document describes the STMAV340 evaluation board, which is designed to facilitate customer testing of the STMAV340 video switch. The board supports two sets of RGB and YPbPr inputs, switching them to a single output, and includes provisions for CVBS inputs. It details the power supply requirements, video port configurations, and digital control signal connections.
| Input voltage (DC adaptor) | 7 to 15 V |
|---|---|
| Blanking level range | 0 V to 2.5 V |
| Number of video channels | 4 channels |
| Video switch function | 2 to 1 video switch |
The DC adaptor should have an output voltage of 7 V to 15 V.
The board has four video input ports: VGA1, VGA2, CVBS1, and CVBS2.
The board can handle video signals with a blanking level of 0 V to 2.5 V.
