1. Description
LT7622UX 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, LT7622UX can be configured as 3/4 lanes. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth up to 18Gbps.
For HDMI2.0 output, LT7622UX can be configured as 3/4 lanes. The maximum bandwidth is up to 18Gbps.
Both HDMI2.0 input and output allow for the highest resolutions of 4K@60Hz.
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, LT7622UX 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 2.5Gbps/lane with D-PHY, which can support a total bandwidth of up to 40Gbps for four port. LT7622UX also support 2.5Gsps/trio with C-PHY, which can support a total bandwidth of up to 68.4Gbps for four port.
For LVDS output, LT7622UX can be configured as single, dual or quad-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 24Gbps. LT7622UX 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.
