DESCRIPTION

· PI3DPX1202A is a DisplayPort 1.2 compliant, low-power DP Redriver.

· It reads Aux-channel Link Training data, configures output swing/pre-emphasis, and calculates EQ via built-in Aux listener.

· EQ can be programmed through the I2C serial interface.

· Reduces signal jitter and compensates for PCB-related losses for optimal DP performance.

FEATURES

· Dual mode DisplayPort Redriver compliant with DP 1.2.

· Supports 1.62/2.7/5.4 Gbps data rates with DDC/Aux signal switching.

· High-speed inputs with internal 50 Ohm pull-down.

· Ultra-low power design.

· Dual mode DisplayPort Input/Output with TMDS clock frequencies up to 340 MHz.

· Aux Listener supports link training, output level, and pre-emphasis setting.

· Pseudo-adaptive equalization based on signal level and pre-emphasis.

· CNTRL pin controls EQ, Output Voltage Swing, and Pre-Emphasis.

· DP and TMDS output mode selection with Cable Detection pins.

· Supports Hot Plug Detect and Cable Detect functions.

· Individual lane power down when no DP signal is present.

· Power down state reduces current consumption when sink device is disconnected.

· 3.3V power supply.

· 2kV ESD HBM protection.

· 48-pin TQFN (7x7mm) package.

APPLICATIONS

· Notebook, AIO, and Desktop PCs.

· Graphic Cards.
