10-Bit Digital Video Decoder with OSD and T-CON

Features

General:

  • No external memory required
  • 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) the 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
  • L-lock system clock frequencies
  • 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
