A product Line of Pb Diodes Incorporated Lead-free Green PI3DPX1202A Low power DisplayPort 1.2 Redriver with DDC/AUX CH Switch Description Typical Applications Notebook, AIO and Desktop PCs PI3DPX1202A is DisplayPort 1.2 standard compliant, very low power DP Redriver. Graphic Cards e deTh vice can read the Aux-channel Link Training (LT)Swing and Pre-emphasis data between Transmitter and Receiver, configure the output swing / Pre-emphasis, and automatically calculates EQ based on Swing/Pre-emphasis LT values through the built-in Aux DP Mainlink(p/n) listener. EQ can program by the I2C serial interface. DP++ Host DP1.2 Redriver CPU + Aux/DDC Switch dGPU e deTh vice can reduce signal jitter caused by transmission line ef- Aux-ch(p/n) fects, and compensate for the PCB-related frequency and switching- DisplayPort related loss to provide optimum DP performance between the link. Connector NoteBook PC DP++ Redriver Features Dual mode DisplayPort Redriver, DP 1.2 Specification compliant Support all 1.62 / 2.7 / 5.4 Gbps data rate with DDC/Aux signal Figure: NB Application Block Diagram switching High speed inputs with internal 50 Ohm pull-down Ordering Information Ultra Low-power design Dual mode DisplayPort Input/Output with TMDS clock Frequencies Package up to 340 MHz Ordering Code Package Type Code Aux Listener support link training and configure output level, pre- emphasis setting during link initialization.
