LT86121GXE

LT86121GXE is a high performance HDMI2.1 or DP1.4a repeater. In long cable application, it should be paired with LT86121GXE.
Both the HDMI2.1 input and output support data rate up to 10Gbps which provides sufficient bandwidth for 4K@144Hz, 8K@30Hz or 8K@60Hz with compression data (pass-through). Also, HDCP2.3 is supported for data decryption and encryption.
Both the Type-C or DP1.4a input and output support data rate up to 8.1Gbps which provides sufficient bandwidth for 4K@144Hz, 8K@30Hz or 8K@60Hz with compression data (pass-through). Also, HDCP2.3 is supported for data decryption and encryption.
In paired mode, DSC 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.
Digital audio output interfaces are available, including I2S/TDM/SPDIF. Two digital audio input interfaces are available, including I2S/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.
