LCOS Frame Rate Converter

General Description

HX7805-A is an active double frame rate converter chip which support ITU601 8 bit 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) Data Enable mode video signals by this chip and then output to drive LCOS RGB and RGBW panel, which type panel can be option by I2C register setting. This chip includes enough memory size that can support VGA, Q720P and QVGA resolutions. 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 are generated by a high performance Phase Lock Loop (PLL) circuits that can convert double frame rate correctly.
