It is compliant with the latest HDMI 2.1a specification and backward compatible with the HDMI 2.0 and HDMI 1.4 specifications.

它符合最新的HDMI 2.1a规范,并向后兼容HDMI 2.0和HDMI 1.4规范。

With 12 Gbps/channel capability, the IT66326 can support ultra-high resolution content streams, such as 8K x 4K video formats.

凭借12 Gbps/通道的能力,IT66326可以支持超高分辨率的内容流,例如8K x 4K视频格式。

All 2 input ports and 1 output port support HDMI 2.1 data rate of up to 48 Gb/s, and the IT66326 also supports various data processing functions, such as video color space conversion function and audio extract/merge function.

所有2个输入端口和1个输出端口都支持高达48gb /s的HDMI 2.1数据速率,IT66326还支持各种数据处理功能,如视频色彩空间转换功能和音频提取/合并功能。

For the audio content in HDMI data stream, the IT66326 can extract the audio from the input stream and/or merge the external audio to the output stream.

对于HDMI数据流中的音频内容,IT66326可以从输入流中提取音频和/或将外部音频合并到输出流。

With the audio extract/merge function, the audio stream from HDMI RX port can be decoded and output to external audio processor through various audio interfaces.

通过音频提取/合并功能,可以对HDMI RX端口的音频流进行解码,并通过各种音频接口输出到外部音频处理器。

After processed by the audio processor, the new audio content can be encoded to audio stream and merged to original video stream from RX port and then a complete video/audio stream can be transmitted by TX port.

新的音频内容经过音频处理器处理后,可以从RX口编码成音频流并合并到原来的视频流中,然后通过TX口传输完整的视频流/音频流。

In some application, the external audio would like to be transmitted by TX port without HDMI input signals.

在某些应用中,外部音频希望通过TX端口传输,而不需要HDMI输入信号。

An embedded pattern generator in IT66326 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IT66326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 IT66326 TX port contains an audio receiver designed for Enhanced Audio Return Channel (eARC) and it is also backward compatible with the HDMI 1.4 Audio Return Channel (ARC).

IT66326 TX端口包含一个专为增强音频返回通道(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, is allowed to receive 8channel 192K or 8-channel 96K 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或8通道96K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 IT66326 also builds in HDCP 1.4/2.3 hardware engines, which can be used to disable the HDCP encryption at the output port or convert HDCP 2.3 to HDCP1.4 for closed system application.

IT66326还内置HDCP 1.4/2.3硬件引擎,可用于在输出端口禁用HDCP加密或将HDCP 2.3转换为HDCP1.4用于封闭系统应用。

Each IT66326 chip comes preprogrammed with a unique HDCP key, in compliance with the HDCP 1.4/2.3 standard so as to provide secure transmission of high-definition content.

每个IT66326芯片都预先编程了一个唯一的HDCP密钥,符合HDCP 1.4/2.3标准,以提供高清内容的安全传输。

Users of the IT66326 need not purchase any HDCP keys or ROMs.

IT66326的用户不需要购买任何HDCP密钥或rom。

The IT66326 also provides a complete solution of Consumer Electronics Control (CEC) function.

IT66326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 specification allows users tol 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 IT66326 embedded CEC PHY, users can use high-level software API to easily implementl all the necessary remote control commands.

使用IT66326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。
