TW2868-LA2-CR

8-Channel Video Decoders and Audio Codecs and  Video Encoder for Security Applications

视频 IC TW2868-LA2-CR 8 CH VID DECODER

The TW2868-LA2-CR TW2868 includes eight high quality  NTSC/PAL/SECAM video decoders that convert  analog composite video signal to digital  component YCbCr data for security applications.  Each channel contains 10-bit ADC and proprietary  clamp and gain controllers and utilizes 4H comb  filter for separating luminance and chrominance  to reduce cross noise artifacts.

Features TW2868-LA2-CR

 Accepts all NTSC(M/4.43) /

PAL(B/D/G/H/I/K/L/M/N/60)/SECAM

standards with auto detection

 Integrated eight video analog anti-aliasing

filters and 10 bit CMOS ADCs

 High performance adaptive 4H comb filters for

all NTSC/PAL standards

 IF compensation filter for improvement of color

demodulation

 Color Transient Improvement (CTI)

 Automatic white peak control

 Programmable hue, saturation, contrast,

brightness and sharpness

 Proprietary fast video locking system

Video Input Formats

The TW2868 has build-in automatic standard discrimination circuitry. The circuit uses burst-phase, burstfrequency and frame rate to identify NTSC, PAL or SECAM color signals. The standards that can be identified are NTSC (M), NTSC (4.43), PAL (B, D, G, H, I), PAL (M), PAL (N), PAL (60) and SECAM (M). Each standard can be included or excluded in the standard recognition process by software control. The exceptions are the base standard NTSC and PAL, which are always enabled. The identified standard is indicated by the Standard Selection (SDT) register. Automatic standard detection can be overridden by software controlled standard selection.
