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.

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.
