2.7SDRAM
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.
2.8Common 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 shares 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.
2.9Video Encoder Analog Outputs
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.
