ADI 视频编码器EI3接口扩展板解决方案

ADI公司的视频编码器EI3扩展板是插在EZ-KIT Lite/EZ评估系统如ADSP-BF609 EZ-KIT Lite®评估系统的扩展接口3(EI3)上的子板,在处理器的并行外设接口(PI)和ADV7511(HDMI发送器)与ADV7341多格式视频编码器之间提供连接,支持EI3标准,而处理器的两线接口(TWI)用来和扩展板的视频编码器和SoftConfig进行通信.译码器采用ADV7842.本文介绍了视频编码器和译码器主要特性,ADV7511和ADV7341主要特性,视频编码器EI3扩展板主要特性,方框图,电路图和材料清单.
The Video Encoder EI3 Extender Board is a separately sold daughter board that plugs onto the expansion interface 3 (EI3) of an EZ-KIT Lite/EZ-Board evaluation system. The extender board aids the design and prototyping phases of embedded processor-targeted applications.
The board extends the capabilities of the evaluation system by providing a connection between the parallel peripheral interface (PPI) of the processor and the ADV7511 and ADV7341 video encoders. The SPORT is used for transmitting audio data. The two-wire interface (TWI) port of the processor is used to communicate to the video encoders and SoftConfig on the Extender.
The following is a list of the Video Encoder EI3 Extender Board interfaces.
• Video interface
• ADV7511 — 225 MHz, high performance HDMI transmitter with ARC
• ADV7341— multi-format video encoder, six 12-bit noiseshaped video DACs
• Video connectors
• One HDMI
• One SVIDEO
• One Component
• One Composite
• No power supply required: derives power from the EZ-KIT Lite/EZ-Board
• CE certified
• Traditional mechanical switches and jumpers for changing the board’s factory setup have been removed in favor of I2C-controlled software switches.
The Video Encoder and Video Decoder EI3 Extender Boards, both EZ-Extender® products, are low cost platforms facilitating the evaluation of video processing on an Analog Devices Embedded Processor via Analog Devices’ EZ-Board development hardware and the CrossCore® Embedded St...
