General Description |
| |
HX7805 is an active double frame rate converter chip which support ITU601 8it YCbCr digital signals and also embedded a de-interlace function. The input signal format is a standard video format that will be double frame rate converted into RGB (8, 8, 8) Date Enable mode video signals by this chip and then output to drive LCOS panel. This chip includes enough memory size that can support VGA resolution. The data inputs of frame buffer memories are written by write clock. Then that are read by read clock at next frame synchronous cycle. However, the memory read clock and write clock and write clock are generated by a high performance Phase Lock Loop (PLL) circuits that can convert double frame rate correctly.
