Key Specifications
This solution supports CVBS, S-video and Component inputs. It decodes NTSC/ PAL/ SECAM from this input interface and converts it into YCbCr 4:2:2 or RGB- 565 digital video data through the programmable data bus.

Features:

a. Analog Input

- Four 10-bit ADC, AGC & ACC (Automatic Clamping Control)

- Supports Auto Multi-Standard NTSC/PAL/SECAM mode detection

- Supports Weak & Non-Standard Signal mode detection

- Adaptive 2D Comb-Filter video decoding for Y/C separation

b. Digital video output

- Supports four digital ITU-R 656 8-bit outputs with four-video-decoder mode.

- Supports two ITU-R 601 16-bit outputs with two-video-decoder mode.

- Supports RGB 565 16-bit output with two-video-decoder mode.

c. Video Processing

- Closed Caption/V-Chip/WSS/WSS-J VBI decoding.

d. 4-Decoder Mode (A,B,C and D)

- 4 analog CVBS inputs for each of the four video decoders

- Standard ITU-R BT 656 format 8-bit outputs

- 4 RTSO (Real Time Status Output) signals for each of the 4 video decoders

- 2 Fast Channel-Switching I/O''s for each decoder

e. 2-Decoder Mode ( AB and CD)

- Each of the 2 video decoders support S-Video and Component inputs

- Standard ITU-R BT 656 format 8-bit outputs

- Standard ITU-R BT 601 format 16-bit outputs

- Digital RGB output ( 8-bit for Green channel,6-bit for Red and Blue Channels )

- 4 RTSO (Real Time Status Output) signals for each of the 2 video decoders

f. Miscellaneous

- 1.8V core logic. 3.3V I/O with 5V tolerance

- Controlled via 2-wire serial-bus interface. All 4 video decoders require only one serial bus and share one slave address

- Requires only one crystal for all 4 video decoders

- Supports interrupt output pin for hardware mode detection

- Built-in Test Pattern Generator

- Low power consumption

- Small-size and Lead Free Package

- LQFP-128 (14x14mm) and LQFP-80 (10x10mm)

Applications:

a. Video Surveillance System

b. Video Editing System
