TVP5158 Evaluation Module

1Description

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. This user guide outlines the necessary hardware and software setup required to provide full evaluation of the TVP5158.

1.1Functional Overview

TVP5158EVM is powered by a single 5-V universal supply. The TVP5158EVM allows the user to have up to four composite video inputs and up to four audio inputs. Analog YPbPr component video output is supported for non-interleaved video modes. Digital video is output to the DaVinci HD EVM in a single or dual ITU-R BT.656 configuration or in ITU-R BT.601 (16-Bit) configuration for evaluation of line-interleaved modes.

The TVP5158EVM uses one PC USB port to provide I2C communication with the TVP5158, THS8200 Video/Graphics Triple DAC and the TLV320DAC32 Stereo Audio DAC devices on the TVP5158EVM. The Video Control Center (VCC) application software is provided for control and evaluation of the TVP5158EVM. A VT100 terminal program is required to connect to the DaVinci HD EVM via UART to send Linux shell commands to control the DSP.

1.2Notational Conventions

This document uses the following conventions.

The TMS320DM6467 Digital Video Evaluation Module is usually referred to as the DaVinci HD EVM. The TMS320DM6467 Digital Media System-on-Chip is usually referred to as the DM6467.
