User's Guide SLEU069A–February 2006–Revised July 2006 TVP5154EVM User's Guide 1 Functional Description The TVP5154EVM evaluation module is a printed circuit board designed for evaluation of the TVP5154 quad video decoder. The board includes the TMS320DM642 digital signal processor (DSP) and is designed 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, w

www.ti.com Board Level Description 2 Board Level Description The TVP5154EVM consists of the TVP5154EVM module and the encoder EVM module. A 4-row 120-pin connector connects the boards. The block diagram of the EVM set is shown in Figure 1. Figure 1. TVP5154EVM Block Diagram 2.1 Test Points and Jumpers 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 fo

www.ti.com Board Level Description 2 Note: If the I C address is changed on either the TVP5154 board or the encoder board while the 2 TVP5154EVM is powered up, that device will not recognize the new I C address. The reset button on the TVP5154EVM must be pressed and WinVCC must be reconfigured for the new 2 I C address. 2.2 Common Board Interface The TVP5154EVM uses a 4-row 120-pin connector to share common signals and the 5-V power supply between the boards. This connection allows multiple back

Typical commercially-available test equipment is also shown. The primary features of this configuration are: • Power is provided by a single 5-V power supply provided with the EVM and is shared between both modules via the 120-pin connector. • Supported analog inputs include composite video and S-video. • Re-encoded composite video and S-video are output via

www.ti.com Software Installation The system comes with the anti-alias filters bypassed. To connect the filters, you must rotate the appropriate jumpers (JP1–JP8) as described in section 2.3. 2 The I 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 selects 0xB8. These are connected to pins 117 and 118, which are read at power up. If you move both the 2 j
