Optimizing Design Through ASIC

Product Brief

TF-680

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.
