3.3V 10Gbps USB Type-C® DP-Alt Linear Redriver with AUX/SBU mux switch. Automotive AEC-Q100 Grade 3 device


PI3DPX1207Q is a USB Type-C DP-Alt mode linear redriver that supports the DP1.4 and USB3.2 spec. for data rates up to 10Gbps with AEC-Q100 grade 3 qualification. It can be configured through the I2C or pin control settings to operate in 4-channel Displayport mode, 1-port USB3.1 Gen2 and 2-channel Displayport mode, 1-port USB3.1 Gen2 mode or 2-port USB3.2 mode. The integrated AUX switch provides the flip function for the side band signal. The Displayport D3 power down function can be activated via the I2C setting or through the built-in AUX listener during pin control mode.

Each of the DP1.4 and USB3.1 Gen2 differential signals can be easily adjusted with equalization, output swing and gain values by the I2C control setting. It can optimize the DP/USB 10Gbps signal performance over a variety of physical mediums by reducing intersymbol interference jitters.

Non-blocking Linear Redrivers provide better additive jitter performance. Linear Equalization does not block the Receiver DFE’s
adaptive channel controls, supporting DisplayPort Transparent LT (Link Training) without dependency of the DP-Aux channels listener.
