PI3VDP411LSTZBE

PI3VDP411LST Digital Video Level Shifter for dual mode DP signals w/ inverting buffer for HPD signal Features Description Converts low-swing AC coupled differential input to HDMI Pericom Semiconductors PI3VDP411LST provides the ability rev 1.3 compliant open-drain current steering Rx terminated to use a Dual-mode Display Port transmitter in HDMI mode. differential output This efl xibility provides the user a choice of how to connect to HDMI level shifting operation up to 2.5Gbps per lane their favorite display. All signal paths accept AC coupled video (250MHz pixel clock) signals. e Th PI3VDP411LST converts this AC coupled signal into Integrated 50-ohm termination resistors for AC-coupled an HDMI rev 1.3 compliant signal with proper signal swing. differential inputs. This conversion is automatic and transparent to the user. Enable/Disable feature to turn off TMDS outputs to enter low- power state. e Th PI3VDP411LST supports up to 2.5Gbps, which provides 12- bits of color depth per channel, as indicated in HDMI rev 1.3. Output slew rate control on TMDS outputs to minimize EMI. Transparent operation: no re-timing or configuration Block Diagram required. 3.3 Power supply required.
