MIK2435B


Introduction

The MIK2435B is a 4-channel video decoder which converts 4 channels of 6.5 MHz analog CVBS signals to 4 channels of digital 27 MHz CCIR656 signals. The MIK2435B integrates two internal PLLs, and decodes 720H videos using the same (27MHz) external clock source. The MIK2435B also features a patented fast switch function. With the fast switch function, the MIK2435B can decode up to 8 analog CVBS with little frame rate loss.

The MIK2435B includes two SD mixers and one HD mixer. Each SD/HD mixer can multiplex up to 4 video sources. In addition to two SD CCIR656 outputs or one HD SMPTE 274M output, the MIK2435B mixer can output four D1 videos through one TDM4 interface. The mixers support image mirror and H partition functions. Both interlaced and progressive digital video outputs are supported.

The MIK2435B also includes five audio ADCs and one audio DAC.
