BIT1605  10-Bit Digital Video Decoder

Features

    Three analog inputs, internal analog source selectors, e.g. 3 × CVBS or 1 × Y/C or ( 1 ×  Y/C and 1 ×

    CVBS)

    Two 10-bit video CMOS Analog-to-Digital Converters (ADCs) in differential CMOS style for best

    S/N-performance

    Fully programmable static gain or automatic gain control (AGC) for selected CVBS or Y/C channel :

    0~12db(Analog) and 0~18db(Digital)

    Automatic Clamp Control (ACC) for CVBS, Y and C

    On-chip clock generator
