Diodes Incorporated has released what is claimed to be the industry's first automotive AEC-Q100 grade 3 qualified 10Gbps USB-C DP-Al) mode linear ReDriver IC. The DP-Alt mode enables the transfer of DisplayPort signals through a USB Type-C connector. Supporting 8.1Gbps DP1.4 and the 10Gbps USB 3.2 specifications, the PI3DPX1207Q gives a transparent, protocol-agnostic ReDriver ability for a range of automotive applications comprising infotainment systems and cluster display panels.


Qualcomm Technologies specifies the device within its Qualcomm Snapdragon ADP for infotainment applications. The ADP is based on the company’s third-generation Qualcomm Snapdragon Automotive Cockpit Platform.


The DP-Alt ReDriver provides ultra-low latency and excellent signal integrity characteristics for up to 8k display resolutions and is completely transparent to channel link training. Each of the 4-to-4 linear differential channels is controllable via I2C commands, incorporating equalisation, gain, and output swing. Controls also include adjusting signal integrity settings for compensation and eliminating intersymbol interference jitter. An integrated AUX switch and AUX listener can monitor for DisplayPort power down commands or a power-down instruction through the I2C interface.


The device, supplied in the 42-TQFN package, supports PPAP documentation and is manufactured in IATF16949 certified facilities.
