Product InformationIT6622: HDMI 1.4 Tx with eARC RX and Embedded MCUThe IT6622 is a HDMI 1.4 Tx with eARC receiver function which supports maximum signaling rate up to 3 Gbps/channel. 
产品信息IT6622: HDMI 1.4 Tx与eARC RX和嵌入式mcu。IT6622是HDMI 1.4 Tx与eARC接收功能，支持最大信号速率高达3 Gbps/通道。

It is compliant with the latest HDMI 1.4b specification and backward compatible with the DVI specifications. 
它符合最新的HDMI 1.4b规范，并向后兼容DVI规范。

With 3 Gbps/channel capability, the IT6622 can support ultra-high resolution content streams, such as 4K x 2K@30 Hz video formats.
凭借3gbps /通道的能力，IT6622可以支持超高分辨率内容流，例如4K x 2K@30 Hz视频格式。

An embedded pattern generator in IT6622 could be used to generate internal video stream which is merged to the external audio stream generated by audio encoder function to form a complete HDMI output signal.
利用IT6622中的嵌入式模式发生器生成内部视频流，并与音频编码器功能生成的外部音频流合并，形成完整的HDMI输出信号。

The IT6622 TX port contains an audio receiver designed for HDMI 2.1 Enhanced Audio Return Channel (eARC) and it is also backward compatible with the HDMI 1.4 Audio Return Channel (ARC). 
IT6622 TX端口包含一个为HDMI 2.1增强型音频返回通道（eARC）设计的音频接收器，它也向后兼容HDMI 1.4音频返回通道（ARC）。

When operating in eARC mode, the Differential Mode Audio Channel (DMAC) bandwidth, i.e. 98.304 Mbps, allows to receive 8-channel 192 K audio from HDMI Sink. 
当在eARC模式下工作时，差分模式音频通道（DMAC）带宽，即98.304 Mbps，允许从HDMI Sink接收8通道192k音频。

No video stream and CEC function is required when eARC link is active.
eARC链路激活时，不需要视频流和CEC功能。

The IT6622 also builds in HDCP 1.4 hardware engines. 
IT6622还内置HDCP 1.4硬件引擎。

Each IT6622 chip comes preprogrammed with an unique HDCP key, in compliance with the HDCP 1.4 standard so as to provide secure transmission of high-definition content. 
每个IT6622芯片都预先编程了一个唯一的HDCP密钥，符合HDCP 1.4标准，以提供高清内容的安全传输。

Users of the IT6622 need not purchase any HDCP keys or ROMs.
IT6622的用户不需要购买任何HDCP密钥或rom。

The IT6622 also provides a complete solution of Consumer Electronics Control (CEC) function. 
IT6622还提供了消费电子控制（CEC）功能的完整解决方案。

This optional CEC feature of HDMI specificationl allows the user to control two or more CEC-enabled devices through HDMI network. 
HDMI规范的可选CEC功能允许用户通过HDMI网络控制两个或多个支持CEC的设备。

With IT6622 embedded CEC PHY, users can use high-levell software API to easily implement all the necessary remote control commands. 
使用IT6622嵌入式CEC PHY，用户可以使用高级软件API轻松实现所有必要的远程控制命令。

The CEC bus related protocol is handled by the CEC PHY which eliminates extra loading of the MCU.
CEC总线相关协议由CEC物理层处理，消除了MCU的额外负载。

With embedded MCU and Flash, customers need no external Flash and MCU, which saves the BOM cost and board size.
采用嵌入式MCU和Flash，客户无需外接Flash和MCU，节省了BOM成本和电路板尺寸。
