LT7941UX — HDMI2.0/DP1.4 with Type-C to Dual-port MIPI/LVDSMixed Switch

1. Description

LT7941UX is a high performance HDMI2.0 or DP1.4a with Type-C to HDMI2.0 and MIPI/LVDS mixed switch chip for Display application.
HDCP RX as the upstream of HDCP repeater, can cooperate with HDCP TX of other chips to realize the repeater function.
For HDMI2.0 input, LT7941UX can be configured as 3/4 lanes. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth up to 18Gbps.
The Type-C/DP1.4a input support data rate up to 8.1Gbps be configured as 1/2/4 lanes. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth is up to 32.4Gbps.
For MIPI output, LT7941UX 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 dual port. Also support 2.5Gsps/trio with C-PHY, which can support a total bandwidth of up to 34.2Gbps for dual port.
For LVDS output, LT7941UX can be configured as single or 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. LT7941UX supports flexible video data mapping path for 2D and 3D applications.
Digital audio output interface is available, including I2S/TDM/SPDIF. Digital audio input interface is available, including I2S/SPDIF.
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.
