Lontium Semiconductor LT6911UXC Datasheet R0.9 features For MIPI DSI/CSI output, LT6911UXC configurable single-port or dual-port MIPI DSI/CSI with 1 high-speed clock lane, and 1~4 high-speed data lanes operating at maximum 2Gbps/lane, which can support a total bandwidth of up to 16Gbps. LT6911UXC supports burst mode DSI video data transferring, also supports flexible video data mapping path. Integrated DSC encoder implements up to 3:1 visually lossless compression which reduces bandwidth requirement for UHD video transport, also power consumption and EMI. 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. 3. Applications  Mobile system  Display  VR 4.
