1. 描述 LT86121EX是一款高性能HDMI2.1中继器，专为长电缆应用而设计。它应该与LT86121EX配对，以达到最长的电缆延伸。 HDMI2.1的输入和输出都支持高达8Gbps的数据速率，这为4K@120Hz视频提供了足够的带宽。HDCP2.3也支持数据解密。 在配对模式下，DSC编码器可以降低数据速率，从而降低带宽要求。 此外，可以激活FEC来纠正数据错误，帮助提高系统容错水平。这些独特的技术将显著延长传输距离。 提供两个数字音频输出接口，I2S和SPDIF。I2S接口支持8通道LPCM, SPDIF接口支持2通道LPCM或压缩音频，采样率均为192khz。 该设备能够自动操作，这是由一个集成的微处理器，使用嵌入式SPI闪存固件存储。系统控制也可通过配置I2C从接口。 LT86121EX采用先进的CMOS工艺制作，采用10mmx10mmqfn88封装。 2. 特性 •HDMI2.1接收机 •HDMI2.1发射机 •数字音频输入和输出 •杂项 3.应用程序 •积极的电缆 •监测 1. Description The LT86121EX is a high performance HDMI2.1 repeater designed for long cable application. It should be paired with LT86121EX for longest cable reach.
Both the HDMI2.1 input and output support data rate up to 8Gbps which provides sufficient bandwidth for 4K@120Hz video. Also HDCP2.3 is supported for data decryption.
In paired mode, DSC encoder can be used to reduce data rate and hence bandwidth requirement.
Furthermore, FEC can be activated to correct data error and help to enhance system error tolerance level. These unique techniques together will significantly extend transmission distance.
Two digital audio output interfaces are available, I2S and SPDIF. The I2S interface supports 8-ch LPCM and the SPDIF interface supports 2-ch LPCM or compressed audio, both at maximum 192 KHz sample rate.
The device is capable of automatic operation which is enabled by an integrated microprocessor that uses an embedded SPI flash for firmware storage. System control is also available through the configuration I2C slave interface.
LT86121EX is fabricated in advanced CMOS process and implemented in 10mmx10mm QFN88 package. 2. Features • HDMI2.1 Receiver
