1. Description

The LT86121TXE is a high performance HD-DVI2.0 repeater designed for long cable application. It should be paired with LT86121RXE for longest cable reach. In paired mode, several unique features can be enabled to reduce bandwidth requirement and optimize performance.
Both the HD-DVI2.0 input and output support data rate up to 6Gbps which provides sufficient bandwidth for 4k@60Hz video. Also HDCP2.2 is supported for data decryption.
In paired mode, YCbCr4:1:1 conversion and 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.
Integrated USB repeater supports high speed, full speed and low speed modes. It is suitable for USB signal extension. User defined packet is also supported which provides a path for sideband data communication.
Two digital audio output interfaces are available, I2S and SPDIF. The I2S interface supports 2-ch LPCM and the SPDIF interface supports 2-ch LPCM or compressed audio, both at maximum 192kHz 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.
