2.1Analog 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. Connector J1 has four analog video (CVBS) inputs (yellow RCA jacks) and four analog audio inputs (white RCA jacks).

2.2Analog Video/Audio Outputs

The TVP5158EVM has a THS8200 Video/PC Graphics Triple DAC and a TLV320DAC32 audio DAC on the board so that the user can evaluate video and audio performance using a single EVM setup. The THS8200 Video/Graphics Triple DAC takes the video output from DVO port A of TVP5158 and outputs analog YPbPr video signals to component output connector J4. The TLV320DAC32 Stereo Audio DAC takes digital audio output from TVP5158 and outputs analog audio to the head phone jack J5.
