7026B-TF

Product Summary

The 7026B-TF is an encoder targeting handheld and similar systems which accept digital input signal, and encodes and transmits data through 10-bit DACs. The 7026B-TF is able to encode the video signals and generate synchronization signals SDTV format for NTSC and PAL standards and HDTV format for 480p,576p,720p and 1080i. Analog RGB output and composite SYNC signal are also supported. The 7026B-TF accepts different data formats including RGB and YCbCr (e.g. RGB565, RGB666, RGB888, ITU656 like YCbCr, etc.). 16Mbit SDRAM is embedded in package. Frame rate conversion and Image rotation are possible.

Features

7026B-TF features: (1)TV encoder targets for handheld device, surveillance camera and automobile market; (2)Supports multiple output formats such as analog TV (NTSC and PAL), VGA and HDTV ( 480p,576p,720p, 1080i). Sync signals can be provided in separated or composite manner; (3)Three on-chip 10-bit high speed DACs providing flexible output capabilities such as single, double or triple CVBS output, YPbPr output, RGB output and simultaneous CVBS and S-video output; (4)90/180/270 degree image rotation and vertical or horizontal flip; (5)16-Mbit SDRAM is used as a frame buffer for frame rate conversion; (6)Flexible up and down scaling; (7)Programmable 24-bit/18-bit/16-bit/15-bit/12-bit/8-bit digital input interface supports various RGB (RGB888, RGB666, RGB565 and etc), YCbCr (4:4:4 YcbCr, ITU656) and 2x or 3x multiplexed input. CPU interface is also supported; (8)Supports flexible input resolution up to 800x800 and 1024x68; (9)Pixel by pixel brightness, contrast, hue and saturation adjustment for each output is supported.
