Offers ultra-low latency and excellent signal integrity characteristics for up to 8k display resolutions for automotive display panels

Providing transparent, protocol-agnostic ReDriver capability for a range of automotive applications including infotainment systems and cluster display panels is the automotive AEC-Q100 grade 3 qualified linear ReDriver IC, the PI3DPX1207Q. It supports 8.1Gbps DP1.4 and 10Gbps USB 3.2 DisplayPort Alternate (DP-Alt) mode. The DP-Alt mode allows the transfer of DisplayPort signals through a USB Type-C connector.

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

Qualcomm Technologies has specified the PI3DPX1207Q within its Qualcomm Snapdragon Automotive Development Platform (ADP) for infotainment applications.

The PI3DPX1207Q, supplied in the 42-TQFN package, supports PPAP documentation and is manufactured in IATF16949 certified facilities of Diodes Incorporated.
