1.1 Features

• Accepts NTSC (M, 4.43), PAL (B, D, G, H, I, M, N), and SECAM (B, D, G, K, K1, L) video data

• Supports ITU-R BT.601 standard sampling

• High-speed 9-bit ADC

• Two composite inputs or one S-video input

• Fully differential CMOS analog preprocessing channels with clamping and automatic gain control (AGC)

for best signal-to-noise (S/N) performance

• Ultralow power consumption: 115 mW typical

• 32-pin TQFP package

• Power-down mode: <1 mW

• Brightness, contrast, saturation, hue, and sharpness control through I2C

• Complementary 4-line (3-H delay) adaptive comb filters for both cross-luminance and cross-chrominance

noise reduction

• Patented architecture for locking to weak, noisy, or unstable signals

• Single 14.31818-MHz crystal for all standards

• Internal phase-locked loop (PLL) for line-locked clock and sampling

• Subcarrier Genlock output for synchronizing color subcarrier of external encoder

• Standard programmable video output format:

− ITU-R BT.656, 8-bit 4:2:2 with embedded syncs

− 8-bit 4:2:2 with discrete syncs

• Macrovision copy protection detection

• Advanced programmable video output formats:

− 2x oversampled raw VBI data during active video

− Sliced VBI data during horizontal blanking or active video

• VBI modes supported

− Teletext (NABTS, WST)

− Closed-caption decode with FIFO, and extended data services (EDS)

− Wide screen signaling, video program system, CGMS, vertical interval tme code

− Gemstar 1x/2x electronic program guide compatible mode

− Custom configuration mode that allows the user to program the slice engine for unique VBI data signals

• Power-on reset
