User's Guide SLEU108 – November 2009 TVP5158 Evaluation Module 1 Description The TVP5158EVM evaluation module is a printed circuit board designed for evaluation of the TVP5158 Four-Channel PAL/NTSC Video Decoder. The TMS320DM6467 DVEVM (digital video evaluation module) can be used with the TVP5158EVM as a back-end video processor.
www.ti.com Board Level Description 2 Board Level Description Figure 1 shows the various features available on the TVP5158EVM. Figure 1. TVP5158 EVM Block Diagram 2.1 Analog Video/Audio Inputs The TVP5158EVM makes use of all the available inputs on the TVP5158 decoder, including four CVBS video inputs and four analog audio inputs.
Board Level Description www.ti.com 2.3 Digital Video/Audio Outputs to DaVinci HD EVM The TVP5158EVM has two dedicated connectors which match the digital video/audio input connectors on the DaVinci HD EVM. Connector J9 includes a 16-bit video data bus (buffered data from DVO_A and DVO_B of TVP5158), OCLK_P, OCLK_N, I2C and interrupts.

Hardware Setup www.ti.com 5.2.1 Additional Setup when DSP Processes Video Only In this configuration, digital video goes to the DaVinci HD EVM. Digital I2S audio goes to the TLV320DAC32 Audio DAC on the TVP5158EVM. Stereo audio output can then be taken from the TVP5158EVM headphone jack.
www.ti.com Hardware Setup 5.2.3.1 DaVinci HD EVM as TVP5158 I2C Master Table 4 describes the jumper settings to set the DaVinci HD EVM as I2C master for the TVP5158. In this case, the Linux application and driver software control the entire system. Audio can be output from the TVP5158EVM or from the DaVinci HD EVM.
