Description
The LT6911GXC is a high performance HDMI2.1 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 HDMI2.1 input, LT6911GXC can be configured as 3/4 lanes. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth is up to 32Gbps.
For MIPI output, LT6911GXC features configurable single-port or dual-port or quad-port MIPIDSI/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. Also support 5.7Gbps/lane with C-PHY, which can support a total bandwidth of up to 68.4Gbps for four port.
For LVDS output, LT6911GXC 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. LT6911GXC 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.
LT6911GXC is fabricated in advanced CMOS process and implemented in 9mmx9mm BGA169 package.2
