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 conversion is automatic and transparent to the user. The PI3VDP411LS supports up to 2.5Gbps, which provides 12bits of color depth per channel, as indicated in HDMI rev 1.3.
