LT7911UXD — DP1.4a/Type-C to Dual-port MIPI with Audio
1. Description
LT7911UXD is a high performance DP1.4a to MIPI chip for automotive and video capture application.
HDCP RX as the upstream of HDCP repeater, can cooperate with HDCP TX of other chips to realize the repeater function.
The Type-C/DP1.4a input 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, LT7911UXD features configurable single-port or dual-port MIPI®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.
LT7911UXD supports flexible video data mapping path for 2D and 3D applications.
Two digital audio interfaces are available I2S/TDM and SPDIF. The I2S/TDM 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.
