Description
Pericom Semiconductor’s PI3VDP411LST provides the ability to use a Dual-mode Display Port 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 PI3VDP411LST converts this AC coupled signal into an HDMI rev 1.3 compliant signal with proper signal swing. This converstion is automatic and transparent to the user.
The PI3VDP411LST supports up to 2.5Gbps, which provides 12-bits of color depth per channel, as indicated in HDMI rev 1.3.
FEATUREs
• Converts low-swing AC coupled differential input to
HDMI rev 1.3 compliant open-drain current steering Rx
terminated differential output
• HDMI level shifting operation up to 2.5Gbps per lane
(250MHz pixel clock)
• Integrated 50-ohm termination resistors for AC-coupled
differential inputs.
• Enable/Disable feature to turn off TMDS outputs to
enter low-power state.
• Output slew rate control on TMDS outputs to minimize
EMI.
• Transparent operation: no re-timing or configuration
required.
• 3.3 Power supply required.
• Integrated ESD protection to 2kV Human Body on all
I/O pins
• DDC level shifters
• Inverting 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
