1. Description
TF-680 is a single chip video streaming SoC that includes video codec and up to 7.1 channels audio. TF-680 supports network connectivity via SDIO or Ethernet interface that enables the different connection methods. TF-680 compresses video and audio data and transmits them to Ethernet or WiFi. It can also decompress video and audio data from WiFi or Ethernet and display them on a TV. Image engine in TF-680 compresses video into MJPEG format and the support resolution of video can be up to 1920x1080 resolution. It decompresses MJPEG files and delivers video to a display. Comparing with other compression methods such as MPEG1/2/4 and H.264, MJPEG delivers very low latency bidirectional interactive mechanism which is the best solution for interactive applications. Lip sync mechanism also designed in the TF-680 guarantees video and audio are in sync.
TF-680 embeds scalar engine that can scale down the captured pictures and then transmits them into network under limited network bandwidth.
Two UART, one I2C and one DDC are used for control purpose. Either AC’97 controller or I2S controller are dedicated for audio input and I2S interface supports up to 7.1 channels audio. The ICE interface provides the easiest way for software engineer to develop firmware and debug it. Ethernet MAC is included in TF-680.
TF-680 has one IR which can be receivers or transmitters. TF-680 has two embedded PLL, one is to generate different timing for different resolution display requirements and the other one is dedicated for SDRAM high performance operations.
