1. Description

LT9712 is a high performance Dual-Port MIPI DPHY/CPHY to DP1.4 and HDMI2.1 or 8-Lane eDP/eDPx converter.
For MIPI DPHY input, LT9712 can be configured as 2 Ports and 1/2/4 lanes per port. Up to 12dB equalization makes it suitable for long distance application and the maximum data rate is 2.5Gbps.
For MIPI CPHY input, LT9712 has 6 data lanes up to 2.5Gsps per data lane, it can be configured as 1/2/3/4 ports. The maximum equalization is 12dB.
For HDMI2.1 output, LT9712 can be configured as 3/4 lanes. The maximum bandwidth is up to 48Gbps. It allow for the highest resolutions of 8K@30Hz or 8K@60Hz with compression data.
For DP1.4a/ eDP1.5 output, it consists of 4 data lanes, supporting 1.62Gbps, 2.7Gbps, 5.4Gbps and 8.1Gbps link rate. The build-in optional SSC function reduces EMI effect. It allow for the highest resolutions of 4K@144Hz or 8K@60Hz with compression data. It can be configured as 8 data lanes for eDP output.
In order to be adaptable to the latest USB Type-C system, LT9712 integrates CC logic and PD controller to relieve mobile system design complexity and BOM cost.
For eDPx output, it consists of 8 data lanes, with operating at maximum 3.7125Gbps per lane, can support 4K@60Hz.
Two digital audio input 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.
