PI3DPX1202A

Low power DisplayPort 1.2 Redriver with DDC/AUX CH Switch

Î ESD HBM protection 2kV

Î Package: 48-pin TQFN (7x7mm)

Description

PI3DPX1202A is DisplayPort 1.2 standard compliant, very

low power DP Redriver.

Typical Applications

e 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.

DPꢂꢂ ꢈoꢉt

e 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.
