PI3VDP1431/PI3VDP1431A
PI3VDP1431/PI3VDP1431A are low power dual mode Dis-
playPort Level Shifters with integrated 3.4Gbps ReDrivers to
improve jitter performance. Input channels has pull down ter-
mination resistors (RT), optimized for DisplayPort level shifter
application.
For mobile platforms, extending battery hours has been one
of the most challenging features. The PI3VDP1431/ PI3VD-
P1431A supports output squelch and or HPD detection (Hot
plug Detect) for smart power management to extend battery
life with <1mA stand-by current.
The device converts the AC and DC coupled input signals to
the compliant signals in the HDMI or dual mode DisplayPort
source systems. Programmable TMDS input signal equaliza-
tion helps to solve the compliance jitter issues, created in the
non-standard HDMI source system with robust ESD/EOS pro-
tection.
