1. Description

The LT7911UX is a high performance Type-C/DP1.4 to MIPI 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 DP1.4 input, LT7911UX can be configured as 1/2/4 lane. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth is up to 32.4Gbps.
For MIPI output, LT7911UX features configurable single-port or dual-port or quad-port MIPI®DSI/CSI with 1 high-speed clock lane and 1~4 high-speed data lanes operating at maximum 2.5Gb/s/lane with D-PHY, which can support a total bandwidth of up to 40Gbps for four port. Also support 5.7Gb/s/lane with C-PHY, which can support a total bandwidth of up to 68.4Gbps for four port.
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.
LT7911UX is fabricated in advanced CMOS process and implemented in 9mmx9mm BGA169 package.
