LT9611UXC Descriptions

The LT9611UXC is a multimedia converter chip manufactured by Lontium Semiconductor Corporation. It is designed to convert MIPI DSI (Display Serial Interface) and CSI (Camera Serial Interface) signals to HDMI 2.0 output. This makes it a valuable component for connecting MIPI-based displays or cameras to HDMI displays or monitors, especially in applications requiring high-resolution video and data transfer.

The MIPI DSI/CSI inputs have configurable single or dual ports with one high-speed clock channel and one to four high-speed data channels, and operate at a maximum rate of 2Gbps/channel, supporting up to 16Gbps of total bandwidth. The LT9611UXC supports burst mode DSI video data transmission and also supports flexible video data mapping paths. The integrated DSC decoder enables up to 1:3 visual lossless decompression, which reduces bandwidth requirements for UHD video transmission, as well as power consumption and EMI.

The HDMI 2.0 output supports data rates up to 6Gbps, providing enough bandwidth for 4k@60Hz video. In addition, HDCP2.2 is supported for data encryption.

Two digital audio inputs are provided: I2S and SPDIF. The I2S interface supports 2-channel LPCM and the SPDIF interface supports 2-channel LPCM or compressed audio, both with a maximum sampling rate of 192kHz.
