PI3VDP411LS
Digital Video Level Shifter from AC coupled
digital video input to a DVI/HDMI transmitter
Features
• Converts low-swing AC coupled differential input to HDMI
rev 1.3 compliant open-drain current steering Rx terminated dif-
ferential output
• HDMI level shifting operation up to 2.5Gbps per lane
(250MHz pixel clock)
• Integrated 50-ohm termination resistors for AC-coupled dif-
ferential inputs.
• Enable/Disable feature to turn off TMDS outputs to enter low-
power state.
Description
Pericom Semiconductor’s PI3VDP411LS provides the ability to
use a Dual-mode DP transmitter in HDMI mode. This flexibility
provides the user a choice of how to connect to their favorite
display. All signal paths accept AC coupled video signals. The
PI3VDP411LS converts this AC coupled signal into an HDMI
rev 1.3 compliant signal with proper signal swing. This conver-
sion is automatic and transparent to the user.
• Output slew rate control on TMDS outputs to minimize EMI.
• Transparent operation: no re-timing or configuration required.
• 3.3 Power supply required.
The PI3VDP411LS supports up to 2.5Gbps, which provides 12-
bits of color depth per channel, as indicated in HDMI rev 1.3.
• Integrated ESD protection to 8kV contact on all high speed
I/O pins (IN_x and OUT_x) per IEC61000-4-2 test spec, level 4
• DDC level shifters from 5V from sink side down to 3.3V on
source side
• Level shifter for HPD signal from HDMI/DVI connector
• Integrated pull-down on HPD_sink input guarantees "input
low" when no display is plugged in
• Packaging (Pb-Free & Green available)

The inputs do not incorporate a squelch circuit. Therefore, we reccomend the input to be externally biased to
prevent output oscillation. Pericom reccomends to add a 1.5Kohm pull-up to the CLK- input.
