4Required Hardware and Equipment

The required hardware and equipment are as follows:

Windows-based PC with Windows XP or later

Video sources (security camera, pattern generator, DVD player, etc.)

Display monitor that supports

1080i component YPbPr video (50 and 60 Hz)

480i and 576i component YPbPr video

Audio amplifier/speakers or headphones

TVP5158EVM (provided)

Cables to provide up to four composite video and up to four audio line inputs

Component Video (YPbPr) cable for output

USB cable (provided)

Universal 5-V power supply (100 to 240 VAC in, 5 VDC/3.0 A out) (provided)

DaVinci HD EVM

Two Samtec HQCD cables

Component video (YPbPr) cable for output

5Hardware Setup

The following sections describe the hardware setup for evaluation of the TVP5158.

5.1Setup for TVP5158EVM Stand-Alone Configuration

For evaluation of video quality, comb filter, noise reduction, auto-contrast and other features, the TVP5158EVM can be setup in a stand-alone configuration. Analog video and audio sources are input to TVP5158. TVP5158 outputs digital video as ITU-R BT.656 or ITU-R BT.601 non-interleaved video to the THS8200 PC Graphics/Video Triple DAC. Component Video YPbPr from the THS8200 is output in 480i or

576i format to a video monitor. To setup the stand-alone 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 TVP5158EVM to video monitor

4.Stereo audio headphone output from TVP5158EVM to audio amplifier/speakers or headphones

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

6.5-V power supply to the dc jack on the TVP5158EVM
