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
The TVP5160EVM uses a 120-pin connector to connect the TVP5160 board to the ADV7311
board. This interface shares all common signals including the I
2
C 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, I
2
C, and 5-V as mentioned above.
2.9
Video 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.
