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
  • Digital PLL for synchronization and clock generation from all standards and non-standard video sources, e.g. consumer grade VTR
  • Requires only one crystal (24.576 MHz) for all standards
  • Automatic detection of 50 and 60 Hz field frequency, and automatic switching between PAL and NTSC standards
  • Accepts NTSC (J, M, 4.43), PAL (60, B, D, G, H, I, M, N), and SECAM (B, D, G, K, K1, L) video signal
  • User programmable luminance peaking or aperture correction
  • Adaptive 3/5-line comb filter for two dimensional chrominance/luminance separation
