TVP5154EVM User's Guide
The TVP5154EVM evaluation module is a printed circuit board designed for evaluation of the TVP5154quad video decoder. The board includes the TMS320DM642 digital signal processor (DSP) and isdesigned with a 120-pin connector, which allows a connection to multiple backends; the evaluation module(EVM) is shipped with a professional encoder module. The board is designed to provide ease of use, whileallowing full evaluation of the video decoder.
The TVP5154EVM uses the PC parallel port to emulate the I
2
C bus, which provides communication withthe TVP5154 video decoder, DM642, and the video encoder. The Windows™ Video Control Center(WinVCC) application software that communicates with the devices via the I
2
C is provided on the EVMCD-ROM.
The analog video inputs supported by the TVP5154EVM include composite video and S-video. More detailabout the video inputs is discussed in section 2.3 Video Input Description. In general, the video decoderconverts the analog video input signal into digital component data. This data and the associated clocksfrom the video decoder are sent to the DM642, which provides various image capture and display modes.The DM642 is setup in I
2
C slave mode and is controlled through virtual I
2
C registers. The video encoderthen converts the digital data from the DM642 back into analog video. The analog video outputs supportedby the EVM include composite video, S-video, and component video. These are all output simultaneously.
To experiment with the programmable features of the TVP5154 video decoder and the video encoder, theparallel port of the TVP5154 is connected to the parallel port of a PC. WinVCC, a Windows-compatibleapplication provides the user interface for performing register-level and high-level control of the TVP5154video decoder and the video encoder.

2.1 Test Points and Jumpers
Board Level Description
The TVP5154EVM consists of the TVP5154EVM module and the encoder EVM module. A 4-row 120-pinconnector connects the boards. The block diagram of the EVM set is shown in Figure 1 .
Figure 1. TVP5154EVM Block Diagram
The TVP5154EVM was designed with test points and jumpers to help in evaluation and troubleshooting.Each jumper is set by default in its preferred state for the TVP5154EVM. There are test points for SCL,SDA, 3.3 V, and 1.8 V. All digital video data for each decoder core are brought out to a dual-row header,which allows easy hookup to test equipment. The I
2
C address selection is made with two shunt jumpers,which are only read after a reset or at power up. The default address is 0xB8. If the address needs to bechanged, the TVP5154 must receive a reset.

Board Level Description
Note: If the I
2
C address is changed on either the TVP5154 board or the encoder board while theTVP5154EVM is powered up, that device will not recognize the new I
2
C address. The resetbutton on the TVP5154EVM must be pressed and WinVCC must be reconfigured for the newI
2
C address.
The TVP5154EVM uses a 4-row 120-pin connector to share common signals and the 5-V power supplybetween the boards. This connection allows multiple backends to be connected to the TVP5154EVM. TheEVM package is shipped with an encoder module. This connector shares all digital video bits (Y[7:0]), allvideo clocks (VS, HS, GLCO/FID, and DATACLK), 5 V, ground, I
2
C bus (SCL and SDA), and reset.
The TVP5154EVM decoder has an analog input channel that accepts two video inputs for each decodercore. The decoder supports a maximum input voltage range of 0.75 V, therefore, an attenuation ofone-half is needed for most input signals with a peak-to-peak variation of 1.5 V. The parallel terminationbefore the input to the device is 75 Ω. The two analog inputs can be connected as either two selectablecomposite video inputs, or one S-video input.
The TVP5154EVM allows the user to have up to two composite inputs or one S-video input for each of thefour-channels. The EVM software sets up and controls this input selection. The S-video input uses twoconnectors, one for the luma channel and one for the chroma channel.
The EVM has a resistor network on each of the inputs. These networks attenuate the signal and allow a75- Ωresistor to ground to be placed after the anti-alias filter for termination.
Each input has an anti-alias filter that can be in-circuit or bypassed by jumpers (JP1–JP8). To select thefilter, the shunts need to be positioned to short positions 1-3 and 2-4. To bypass the filter, the shunts needto be moved to short positions 1-2 and 3-4 as shown in Figure 2 . The boards are shipped with the filterbypassed.
Figure 2. Anti-Aliasing Filter Selection
The 8-bit digital video outputs of the TVP5154 are routed to the four 32-pin headers (H2–H5), the DM642,and finally to the 120-pin edge connector along with all video clocks on the TVP5154 module. Theencoder module connects to the 120-pin connector, and is capable of receiving digital video with orwithout embedded syncs. The analog outputs of the encoder module are composite, S-video, andcomponent. For the user’s convenience, all of these outputs come out of the encoder modulesimultaneously.

Software Installation
The system comes with the anti-alias filters bypassed. To connect the filters, you must rotate theappropriate jumpers (JP1–JP8) as described in section 2.3.
The I
2
C slave address can be selected with jumpers JP9 and JP10. There are four possible addresses:B8, BA, BC, and BE. The default setting for these jumpers is for the shunt to short pins 2-3, which selects0xB8. These are connected to pins 117 and 118, which are read at power up. If you move both thejumpers to positions 1-2 and reset the board, the video decoder now responds to I
2
C slave address 0xBE.If you choose to change the address, you must exit, restart WinVCC, and configure the software to usethe new I
2
C slave address.
WinVCC is a Windows application that uses the PC parallel port to emulate I
2
C, providing access to eachdevice on the I
2
C bus. WinVCC makes use of CMD files, a text editable file that allows preset videosetups to be programmed easily.
This feature allows the user to easily set multiple I
2
C registers with the press of a button. WinVCC alsohas property sheets for the TVP5154, which allows the user to control the I
2
C registers with a GUI.
All necessary software for the TVP5154EVM is provided on the enclosed CD. Perform the following stepsto install WinVCC:1. Explore the provided TVP5154EVM Software CD.2. Install Port95NT.exe. This is the parallel port driver used by WinVCC. This driver must be installed andthe PC must be rebooted before WinVCC operates correctly. This does not affect normal parallel portoperation.
3. Install Setup.exe. Click Next at all prompts and click Finish to complete the installation process. Thisinstalls WinVCC onto the PC. No reboot is required.4. Run WinVCC.exe.
Note: A shortcut to WinVCC should now be available on the desktop. WinVCC and additionalTVP5154-related documentation can also be found at Start →Programs →TVP5154EVMSoftware.
Perform the following steps in order to see a video output from the TVP5154EVM.1. Once WinVCC is executed, the WinVCC Configuration screen appears, as shown in Figure 4 . Thisdialog box configures the I
2
C bus. Next to VID_DEC, select the TVP5154 and ensure the I
2
C addressis set to 0xB8 (default setting on EVM.) This must match the I
2
C ADDR jumper on the TVP5154 board.2. Next to VID_ENC, select the 7311 Encoder and ensure the I
2
C address is set to 0x54 (default settingon EVM.) This must match the I
2
C ADDR jumper on the encoder board.
Note: If WinVCC is running and the TVP5154 or encoder board I
2
C address is changed, powermust be cycled on the EVM.
