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 8k@30Hz 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.
