1. Description
LT6911GXD is a high performance HD-DVI2.1 or 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 HD-DVI2.1 input, LT6911GXD can be configured as 3/4 lanes. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth up to 40Gbps.
Both the DP1.4a or Type-C input and output support data rate up to 8.1Gbps which provides sufficient bandwidth for 4K@120Hz, 8K@30Hz or 8K@60Hz with compression data (pass-through).
For MIPI output, LT6911GXD 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 5.7Gbps/lane with C-PHY, which can support a total bandwidth of up to 34.2Gbps for dual port.
For LVDS output, LT6911GXD 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 12 Gbps. LT6911GXD 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.
