TAIFATECH PC TO TV

TF-680 is a single chip HD streaming SoC that includes HD video codec and up to 7.1 channels
audio. TF-680 supports network connectivity via SDIO, USB 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 HDTV 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.
