1. Description
LT7911UXD is a high performance Type-C/DP1.4a to MIPI or LVDS chip for VR/Display application.
HDCP RX as the upstream of HDCP repeater, can cooperate with HDCP TX of other chips to realize the repeater function.
For DP1.4a input, LT7911UXD can be configured as 1/2/4 lanes. Adaptive equalization makes it suitable for long cable application and
the maximum bandwidth up to 32.4Gbps.
For MIPI output, LT7911UXD features 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 2.5Gbps/lane with D-PHY, which can support a total bandwidth of up to 20Gbps for four
port. LT7911UXD also support 5.7Gbps/lane with C-PHY, which can support a total bandwidth of up to 34.2Gbps for two port.
For LVDS output, LT7911UXD can be configured as single, dual-port LVDS with 1 high-speed clock lane, and 3~5 high-speed data
lanes, operating at maximum 1.2Gbps per lane, which can support a total bandwidth of up to 12Gbps. LT7911UXD supports flexible
video data mapping path for 2D and 3D applications.
Two digital audio 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.
