HDMI conversion chip - MS1858

  MS1858 is a single-chip CVBS/S-Video to HDMI converter, which integrates 9-bit video ADC, 24-bit audio ADC and HDMI 1.3 transmitter. MS1858 has 3D video decoding, high-performance OSD, DMC, video scaling and high-speed analog switch, at the same time, it provides frame rate conversion and deinterlacing progressive scan conversion. MS1858 supports master and slave modes. In master mode, it can be configured through internal MCU and ROM or external EEPROM according to user needs; in slave mode, it needs to be configured through an external controller. Master and slave mode selection needs to set the corresponding pin state.
