The (B/D/G/H/I/K/L/M/N/60) standard formats with TW280X contains four 10-bit A/D and proprietary digital auto detection gain/clamp controllers and uses proprietary techniques Four 10-bit video CMOS analog to digital for separating luminance and chrominance to reduce converters both cross-luminance and cross-chrominance artifacts. Adjust video level with proprietary automatic The high performance dual scalers in each channel clamp and gain control system offer two differently scaled video outputs with 54MHz Proprietary architecture for locking to weak, noisy, ITU-R BT.656 format for security system design. Four or unstable signals built-in motion detectors can also increase the feature High performance adaptive comb filters for all of security system. NTSC/PAL standards IF compensation filter for improvement of color Applications demodulation Security systems PAL delay lines for correcting PAL phase errors Programmable hue, saturation, contrast, Device Options brightness and sharpness Device Name Features Dual high quality horizontal and vertical down TW2802 Two-Channel Video Decoder scaler for each channel TW2804 Four-Channel Video Decoder Four built-in motion detectors for security system Supports the standard ITU-R BT.656/8-bit ITU-R BT.601 format Supports two differently scaled output mode with 54MHz ITU-R BT.656 format Supports a two-wire serial or parallel interface Low power consumption 128 PQFP package FN7732 Rev.1.00 Page 1 of 81 May 19, 2017 TW2802, TW2804 Table of Contents SPTSENS (Spatial Sensitivity) 20 Block Diagram 3 TMPSENS (Temporal Sensitivity) 20 Velocity Control 21 Pin Configuration 4 Mask Detection Region 22 Pin Description 5 Output Format 23 Analog Interface Pins 5 ITU-R BT.656 Format 23 8-bit ITU-R BT.601 Format 24 Digital Data Interface Pins 6 Dual ITU-R BT.656 Format in 54MHz 25 System Control Pins 7 Host Interface 26 Power/Ground Pins 7 Serial Interface 26 Functional Description 8 Parallel Interface 27 Video Input Formats 8 Interrupt Interface 28 Analog-to-Digital Converter 8 Control Register 29 Sync Processing 9 Register Map 29 Video Level Adjustment 9 Recommended Value 31 Horizontal Sync Processing 9 Register Description 33 Vertical Sync Processing 9 Parametric Information 69 Color Decoding 10 DC Electrical Parameters 69 Decimation Filter 10 Y/C Separation 11 AC Electrical Parameters 71 Luminance Processing 12 Package Dimension 75 Chrominance Processing 13 Application Information 77 Chrominance Demodulation 13 ACC (Automatic Color gain control) 14 Video Input Interface 77 Chrominance Gain, Offset and Hue Adjustment Clamping / AGC 77 14 Video Output Interface 77 Video Scaling and Cropping 15 Video Scaling 15 Power-Up 77 Video Cropping 18 Application Schematic 78 Motion Detector 20 Revision History 79 Sensitivity Control 20 81 LVLSENS (Level Sensitivity) 20 FN7732 Rev.1.00 Page 2 of 81 May 19, 2017
