NS5730/NS5734 AVTuHD 发射芯片

Introduction

NS5730/NS5734 are 4Kx2K video transmitters supporting Advanced Video Transport (AVT) technology with visually lossless digital video compression. Furthermore, the AVT technology supports configurable compression ratio based on cable quality and cable length to obtain the best image quality.

NS5730/NS5734 can extend the reach of 4Kx2K video over 100meters. The chips support both single-ended coaxial cable and twisted pair cable.

NS5730 supports up to 4Kx2K@30Hz, 2560x1440@60Hz and 1080P@144Hz, NS5734 supports up to 4Kx2K@60Hz, 2560x1440@144Hz and 1080P@240Hz.

NS5730/NS5734 include a flexible 24-bit video data interface capable of accepting various video formats compatible withCEA-861 and VESA Specification. They can also support four SPDIF inputs for 8-channel LPCM or compressed audio stream, and four I2S inputs for 8-channel LPCM up to 192 KHz audio sampling rate.

NS5730/NS5734 also support reverse audio and control data transmission, and integrates a reverse direction signal receiving circuit, which makes it capable to transmit video, audio and control signals in forward direction (downstream) while receiving reverse (upstream) audio and control signals transferred on the same cable simultaneously.
