1. Description

The LT8711GX is a high performance Type-C/DP1.4a to HDMI2.1 converter, designed to connect a USB Type-C source or a DP1.4a source to an HDMI2.1 sink.
The LT8711GX integrates a DP1.4a compliant receiver, and an HDMI2.1 compliant transmitter. Also, one CC controller is included for CC communication to implement DP Alt Mode and power delivery function, because it is one DRP (Dual Role port).
For DP1.4a input, LT8711GX can be configured as 1/2/4 lanes. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth is up to 32.4Gbps.
For HDMI2.1 output, LT8711GX can be configured as 3/4 lanes. The maximum bandwidth is up to 32Gbps. It allow for the highest resolutions of 8K@30Hz or 8K@60Hz with compression data.
Two digital audio input or 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.
