BIT1603

10-Bit Digital Video Decoder

Features

  • Two analog inputs, internal analog source selectors, e.g. 2 × CVBS or 1 × Y/C
  • 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
  • PAL delay line for correcting PAL phase errors
  • Brightness, Contrast, Saturation (BCS) and Hue control on-chip
  • Two multi functional real-time output pins controlled by TWSI bus
  • Multi-standard VBI-data slicer including closed caption.
  • MV copy protection detection
  • Standard ITU 656 YUV 4 : 2 : 2 format (8-bit) on output bus
  • TWSI controlled (full read-back ability) by an external controller, bit rate up to 400 Kbits/s
  • Auto blank screen when signal un-lock
  • Built-in 4 types (Pure color, Ramp, Grid and Color Bar) TV pattern
  • User programmable sharpness filter
  • User programmable U/V Gain and CTI function
  • Pin options at power-on reset stage
  • Low power consumption and low operating voltage design (1.8V / 3.3V)
  • Small package (TQFN32)
  • 5 V tolerance digital I/O ports
