1. Description

The LT8711UX is a high performance Type-C/DP1.2 to HDMI2.0 converter, designed to connect a USB Type-C source or a DP1.2 source to an HDMI2.0 sink. The LT8711UX integrates a DP1.2 compliant receiver, and an HDMI2.0 compliant transmitter. Also, two CC controllers are included for CC communication to implement DP Alt Mode and power delivery function, one for upstream Type-C port and another for downstream port.
The DP interface comprises 4 main lanes, AUX channel, and HPD signal. The receiver supports maximum 5.4Gbps (HBR2) data rate per lane. The DP receiver incorporates HDCP 1.3 content protection scheme with embedded key for secure transmission of digital audio-video content.
The HDMI interface includes 4 TMDS clock/data pairs, DDC, and HPD signal. The HDMI transmitter is capable of supporting up to 6Gpbs data rate, quite adequate for handling video resolutions up to UHD 4k 60Hz formats. The HDMI transmitter incorporates HDCP engines which support both HDCP1.4 and HDCP2.2. With the inclusion of HDCP, the LT8711UX allows secure transmission of protected content. Embedded key is available that provides the highest level of HDCP key security.
Besides digital video output interface, the LT8711UX also provides digital audio output interfaces: I2S and SPDIF. The audio stream is extracted and recovered from DP data stream, and then routed to digital audio outputs or HDMI output. The device supports 2-channel LPCM or compressed audio 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 use of a dedicated configuration I2C slave interface.
