3System-Level Description

A system-level block diagram incorporating the TVP5154 is shown in Figure 3. Typical commercially-available test equipment is also shown. The primary features of this configuration are:

∙Power is provided by a single 5-V power supply provided with the EVM and is shared between both modules via the 120-pin connector.

∙Supported analog inputs include composite video and S-video.

∙Re-encoded composite video and S-video are output via the encoder module.

∙Component (YPbPr) video is output via the encoder module.

∙I2C bus initializes the video devices via a PC parallel port.

∙The TVP5154 video decoder performance parameters may be measured with a video analyzer.

5Hardware Setup

Figure 1 shows the TVP5154EVM layout and indicates the location of the power supply and the appropriate connectors. All connectors are labeled according to their function. To prepare the EVM for evaluation, connect the following:

1. TVP5154 module to encoder module

2. Parallel port cable from TVP5154EVM to the PC

3. Analog video sources to TVP5154EVM inputs

4. Analog video out from TVP5154EVM to monitor

5. 5-V power supply to the dc jack on the TVP5154 board. A green LED on each board should now be lit.
