PI3DPX1202A

Low power DisplayPort 1.2 Redriver with DDC/AUX CH Switch

Description

PI3DPX1202A

DisplayPort 1.2 standard compliant, very

low power DP Redriver.

The device 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 listener. EQ can pro-

gram by the I2C serial interface.

The device can reduce signal jitter caused by transmission

line effects, and compensate for the PCB-related frequency

and switching-related loss to provide optimum DP perfor-

mance between the link.

ESD HBM protection 2kV

Package: 48-pin TQFN (7x7mm)

Typical Applications

Notebook, AIO and Desktop PCs

Graphic Cards

DP Mainlink(p/n)

DP++ Host

CPU

dGPU

DP1.2 Redriver

+ Aux/DDC Switch

DisplayPort

Connector

NoteBook PC DP++ Redriver

Aux-ch(p/n)

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 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 support link training and configure output

level, pre-emphasis setting during link initialization.

Aux Listener supports "sink Request test mode"

Pseudo-adaptive equalization based on signal level and

pre-emphasis setting in Aux register

CNTRL provides pin control EQ, Output Voltage Swing

and Pre-Emphasis

DP and TMDS output mode selection with Cable

Detection pins

Support Hot Plug Detect and Cable Detect function

Individual lane power down automatically when no DP

signal present

DP redriver enter power down state to reduce current

consumption when sink device deserted

Power Supply : 3.3V
