5.2Setup for TVP5158EVM with DaVinci HD EVM

The TMS320DM6467 DVEVM (digital video evaluation module) can be used as the audio/video back-end processor for evaluation of TVP5158. This EVM is available separately from Texas Instruments and is referred to as the DaVinci HD EVM in this document.

This configuration allows evaluation of all line-interleaved video output formats with up to four channels in D1, Half-D1 or CIF resolution. Eight-channel line-interleaved video is also possible if two TVP5158EVM boards are cascaded together.

Sample video and audio driver code and a demo application are provided to run on the TMS320DM6467 on the Linux O/S.

To setup the TVP5158EVM with DaVinci HD EVM configuration, make the following connections:

1.Analog video sources to TVP5158EVM composite video inputs (see Figure 3)

2.Analog audio sources to TVP5158EVM audio line inputs (see Figure 3)

3.Analog component YPbPr video out from DaVinci HD EVM to monitor

4.USB cable from PC to TVP5158EVM. A green LED should be lit indicating that the EVM is ready for communication on the USB.

NOTE: If the VCC GUI Software for TVP5158 is not used, it is not necessary to connect the

TVP5158EVM to a PC USB port.
