1 Functional Description
The TVP5160EVM refers to both the TVP5160 board and the ADV7311 board when they are connected together. Both boards share a common interface via a 120-pin connector. This interface provides all data, clocks, I2C communication, and 5-V power to each board.
The ADV7311 is a professional grade, 12-bit, 216-MHz, video encoder. This device minimize s potential artifacts caused by the re-encode process. When evaluating the TVP5160 decoder, it is highly recommended that the YPbPr component video outputs of the ADV7311 be used. This will ensure the video decoder within the display monitor will not be used.
1.1 Description Overview
The TVP5160EVM is powered by a single, 5-V, universal supply. I2C communication is emulated using a PC parallel port configured for ECP (extended capability port) or bidirectional mode. The parallel port mode can be changed using the PC BIOS setup, available during the reboot process.
The TVP5160 video decoder converts the analog video input signal into digital component data. This digital data and the associated clocks from the video decoder are sent to the ADV7311 video encoder. The video encoder converts the digital data back into analog video. The analog video outputs provided by the ADV7311 encoder include CVBS, S-Video (SV), and YPbPr. These are all output simultaneously.
SLEU063
Control of the TVP5160EVM is provided by WinVCC4, a Windows-based application developed by Texas Instruments and provided free of charge. This application uses the parallel port to provide I2C communication to the TVP5160EVM. WinVCC4 provides a graphics user interface (GUI) and a register level interface to program and vary the controls available within the TVP5160 decoder and the ADV7311 encoder.

2.2 Anti-Aliasing Filters
Each analog input has an anti-alias filter installed by default to ensure the input to the TVP5160 decoder is of the best quality and does not alias. The filters are elliptical in design in order to minimize the cost and still provide the best roll-off. Details on the anti-aliasing filters, including frequency response and the group delay , are provided in a separate application note.
The filter on any analog input may be bypassed by removing the 0-? resistors currently installed (JP1-6, 9, 10) and shorting one of them across 1-2. Since the S-Video input is shared with the SCART (CVBS and R), these inputs share the same anti-aliasing filters.
SLEU063
2.3 Analog Output
The analog output from the TVP5160 decoder is ma de available on the TVP5160EVM. The output is buffered using a simple emitter follower and the output signal is automatically determined by the TVP5160 decoder. If a CVBS is selected as the input, then the analog output is the same looped-through CVBS output. If S-Video or YPbPr is the selected input, then only Y is output since it contains the sync information. Typically , the analog output is used for VCR record funct ions in some CE applications.
2.4 Tuner Interface
The tuner interface provides a method of connecting an analog TV tuner to the TVP5160EVM. The expected output from the tuner module to the TVP5160EVM is baseband composite video. Termination for the 75 -? input source is already provided on the TVP5160EVM tuner input. The pinout of the tuner interface is provided in Table 2.
Table 2. Tuner Interface Pinout (H2)
Description Pin Number
CVBS output (from tuner) 10 SDA (I2C data) 29 SCL (I2C address) 31 GND 1-9, 11-28, 30, 32-36 D5V 37-40
To supply the tuner module, D5V supply and GND pins are provided. The I2C pins, SDA and SCL, are connected to the I2C communications bus on the TVP5160EVM. Control of the tuner module is available within the TVP5160EVM software as discussed later.
TVP5160EVM User’s Guide 5
SLEU063
2.5 VBI Decoder Interface
This interface provides a method of connecting an external VBI decoder module to the TVP5160EVM via the H3 and H4 headers. The VBI decoder may be a closed-caption decoder, teletext decoder, or any other VBI decoder currently available on the market that provides the same signals. The pinout of the VBI decoder interface is provided below.
Table 3. VBI Decoder Interface Pinout
Description H3 Pin Number H4 Pin Number
Tuner CVBS input (from tuner I/F) 1 ­CVBS input (from TVP5160EVM) 3 ­Analog RGB 11, 9, 7 (R, G, B) ­HSYNC 4 ­VSYNC 6 ­FSS (for analog overlay) 10 ­Digital RGB - 7, 9, 11 (DR, DG, DB) SDA (I2C data) - 8 SCL (I2C address) - 10 FSO (for digital overlay) - 12 GND 2, 5, 8, 12 5, 6 D5V - 1-4
With this interface , there are two methods of overlaying the RGB character data output from the VBI decoder onto the input signal to the TVP5160 decoder:
? Analog RGB overlay ? Digital RGB overlay
Separate sets of the RGB inputs are provided depending on which overlay method is preferred. The analog RGB inputs are connected to the TVP5160 analog inputs as discussed in Section
2.1. The digital RGB inputs and FSO are connected to the digital R, G, and B inputs and FSO which are shared with the C bus, C6-9, respect ively.
2.6 Test Points and Jumpers
Various test points are available on the TVP5160EVM for the user. This includes the various power supplies as well as a few GND test points. The primary test-point header is H6 and provides access to the video data, video clocks, I2C, 5 V, and GND.
There are three jumpers available on the TVP5160 board that configure the power down mode, I2C address select, and the FSS select. Each jumper is set by default in its preferred state for the TVP5160EVM. Next to each jumper on the TVP5160 board is the silkscreen that describes the two states of the jumper configuration.
If the I2C address is changed on either the TVP5160 board or the ADV7311 board while the TVP5160EVM is powered up, then that device will not recognize the new I2C address. The reset button on the TVP5160EVM must be pressed and WinVCC4 must be reco nfigured for the new I2C address.
6 TVP5160EVM User’s Guide
2.7 SDRAM
On the TVP5160EVM , there are three SDRAM footprints: 50-pin, 54-pin, and 86-pin. These are provided to accommodate the user’s choice of SDRAM that will be used in their final product. By default, the TVP5160EVM is provided with 64-Mbit SDRAM (54TSOPII).
If the SDRAM is changed, then the SDRAM configuration register (0x59) will also need to be updated with the correct memo ry size. This must be programmed before 3DYC or 3DNR is enabled.
2.8 Common Board Interface
The TVP5160EVM uses a 120-pin connector to connect the TVP5160 board to the ADV7311 board. This interface shares all common signals including the I2C and the 5-V supply. The purpose is to modularize the TVP5160 board and allow users to interface it to a variety of other Texas Instruments products including triple video DACs, DVI transmitters, or to any other platform that shares the same interface.
This connector sh ares all digital video data (Y[9:0], C[9:0]), all video clocks (SCLK, VS, HS, GLCO, AVID, and FID), reset, I2C, and 5-V as mentioned above.
2.9 Video Encoder Analog Outputs
SLEU063
The analog outputs of the ADV7311 board include CVBS, S-Video, and YPbPr. All of the outputs are available simultaneously. For evaluation purposes, it is recommended that the YPbPr component video outputs be used in order to bypass the video decoder internal to the display monitor.
TVP5160EVM User’ s Guide 7
SLEU063
3 System Level Description
The system block diagram illustrated in Figure 2 provides an example of how the TVP5160EVM may be used for evaluation. Typically , the analog input is a CVBS signal provided by a video source such as a pattern generator or a DVD player running a test DVD.
The TVP5160EVM itself is configured with the provided 5-V supply and the parallel port cable. The analog output is typically YPbPr to reduce the number of artifacts caused by backend processing or re-encoding. These outputs are then fed into a high-end or studio-quality display monitor such as a Sony Trinitron.
At the same time, the CVBS output from the encoder may also be fed into a video test measurement system such as the Tektronix VM700. This allows various tests to be run and also allows the user to analyze the video waveform or vectorscope.

SLEU063
8.2 WinVCC4 Configuration Dialog Box
The WinVCC4 Configuration dialog box, as seen in Figure 8, should now be visible. This dialog configures the I2C bus on the TVP5160EVM. All settings from this dialog box are stored in the Windows registry and are restored the next time the program is started. After initial installation, VID_DECTM will be set to TVP5160 and VID_ENC will be set to ADV7311.
The I2C slave address for each device must match the I2C slave address selected by jumpers on the TVP5160EVM. These jumpers are set by the factory to use 0xB8 for the video decoder and 0x54 for the video encoder.
It is also important to select the correct specific devices. The TVP5160 and ADV7311 must be selected for the TVP5160 EVM.
All Program Options must be enabled. Disabling these options is only required if you are debugging a problem with the I2C bus itself.
Clicking OK begins I2C communication with the selected devices.
Figure 8. WinVCC4 I2C Address Configuration
16 TVP5160EVM User’s Guide
8.3 I2C System Test
The I2C system test of selected registers runs immediately after closing the WinVCC4 Configuration dialog box with OK (unless the I2C system test program options button was
disabled). If the I2C system test passes, then only a PASS message will appear. If the test failed, then a
dialog box like Figure 9 wi ll appear. See Section 9, Troubleshooting, for details on how to resolve this issue.
The I2C system test can be run at anytime by clicking Run System I2C Test in the Tools menu.
SLEU063
8.4 Real-Time Polling
Real-time polling provides polling functions that execute in the background continuously, when enabled via the Real-Time Polling dialog. There are two polling functions. The function that applies to the TVP5160 decoder is VIDEO–STANDARD AUTO–SWITCH POLLING.
When the TVP5160 decoder detects a change in the input video standard, it automatically switches to operation in the detected standard (which includes all necessary I2C register initialization) for proper decoding of the input video. The ADV7311 encoder does not have this feature. For this reason WinVCC4 must update the video encoder.
