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. This user guide outlines the

necessary hardware and software setup required to provide full evaluation of the TVP5158.

1.1 Functional 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.

1.2 Notational 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.

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. Connector J1 has four analog video (CVBS) inputs (yellow RCA

jacks) and four analog audio inputs (white RCA jacks).

2.2 Analog 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.

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. The connector J10 includes BCLK, LRCLK

and SD_R/SD_M outputs from TVP5158. Samtec HQCD cables are required to connect TVP5158EVM

digital video and audio signals to the DaVinci HD EVM.

2.4 Digital Video/Audio Cascade Output/Input

The TVP5158EVM has two connectors for video/audio cascade mode test. The connector J2 is for

video/audio cascade output, which includes buffered data from the DVO_A and DVO_B video output ports

and audio cascade output from TVP5158. The connector J3 is for video/audio cascade input, which

includes video input data to the DVO_C and DVO_D video ports and audio cascade input from a lower

cascaded stage TVP5158 device.

2.5 I2C Configuration Options

The TVP5158EVM uses one PC USB port for I2C communication. The I2C bus master can be changed

based on jumper settings. Control is via the PCB USB interface (VCC application controls TVP5158), via

the DaVinci EVM (DSP driver software controls TVP5158) or via the cascade input/output connectors J3

or J2.

2.6 Test Points and Jumpers

Various test points are available on the TVP5158EVM for the user. This includes the various power

supplies as well as a few GND test points. The user can also use J2/J3 for primary test-point headers to

access video/audio data, video/audio clocks, I2C and GND.

There are several jumpers available on the TVP5158EVM that configure I2C address select, I2C control

configuration, clock source selection and I2S source select. Each jumper is set by default in its preferred

state for the TVP5158EVM. Next to each jumper on the TVP5158EVM is the silkscreen that describes the

various jumper configurations. If the I2C address is changed on the TVP5158EVM while the

TVP5158EVM is powered up, then that device will not recognize the new I2C address. The reset button

on the TVP5158EVM must be pressed and the VCC application must be exited, restarted, and

re-configured for the new I2C address. Table 1 shows the TVP5158EVM jumper settings.

3 System Level Description

The system block diagram illustrated in Figure 2 provides an example of how the TVP5158EVM may be

used for evaluation. Typically, the analog video/audio input is provided by a video source such as a

pattern generator or a DVD player running a test DVD. The TVP5158EVM is configured with the 5-V

supply and the USB cable provided.

The TVP5158EVM analog video output is standard definition component video (YPbPr). These outputs

are then fed into a high-end or studio-quality NTSC/PAL monitor.

The user can also connect the TVP5158EVM to a DaVinci HD EVM and then output combined video from

the DaVinci HD EVM to a 1080i HD monitor.

5 Hardware Setup

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

5.1 Setup 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.
