SLEU063 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 2 interface provides all data, clocks, I C communication, and 5-V power to each board. The ADV7311 is a professional grade, 12-bit, 216-MHz, video encoder. This device minimizes potential artifacts caused by the re-encode process. When evaluating the TVP5160 decoder, it is highly r

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 -

SLEU063 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 memory size. This must be programmed before 3DYC or 3DNR is enabled. 2.8 Common Board Interface T

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

SLEU063 5 Hardware Setup The following describes how to set up the hardware for the TVP5160EVM. 1. Connect the TVP5160EVM boards together using the 120-pin board connector on each board. 2. Connect a CVBS input to the TVP5160 board and a component cable to the YPbPr outputs of the ADV7311 board. NOTE: For evaluation it is recommended that the YPbPr component video outputs be used in order to bypass the internal video decoder of the TV or video display. 3. Connect the parallel port cab

SLEU063 6 Software Installation 2 WinVCC4 is a Windows application that uses the PC parallel port to emulate I C, providing 2 access to each device on the I C bus. WinVCC4 makes use of CMD files, a text editable file that allows preset video setups to be programmed easily. 2 This feature allows the user to easily set multiple I C registers with the press of a button. 2 WinVCC4 also has “Property Sheets” for the TVP5160 which allows the user to control the I C registers with a GUI.

SLEU063 7 WinVCC4 Quick Start The following describes the steps to take within WinVCC4 in order to get video out of the TVP5160EVM. 1. Once WinVCC4 is executed, the WinVCC4 Configuration screen appears. This dialog 2 box is used to configure the I C bus. Next to VID_DEC, select the TVP5160 and ensure 2 the I C address is set to 0xB8. This should match the I2C ADDR jumper on the TVP5160 board. 2 NOTE: If WinVCC4 is running and the TVP5160 board I C address is changed, power must be

SLEU063 If the WinVCC4 autoswitch polling function is enabled, then the detected video standard status from the TVP5160 decoder is polled until a change in the input video standard (or in the TVP5160 sampling mode) is detected. When a change is detected, the video encoder is reprogrammed as needed for the detected standard. Using this feature, the video source can change its video standard and the system will display using the new standard without user intervention. To enable autoswitch
