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
