HDMI 2.0/DisplayPort 1.2a, 6.0 Gbps 2:1/1:2 Differential Switch



HD3SS215 is a high-speed wide common mode passive switch capable of supporting DisplayPort HBR2 and high definition multimedia interface (HDMI) applications requiring 4k2k 60Hz refresh rates. The HD3SS215 can be configured to support two sources to one sink or one source to two sinks. To support these video standards the HD3SS215 also switches the display data channel (DDC) and hot plug detect (HPD) signals for HDMI or digital video interface (DVI) applications. It also switches the auxiliary (AUX) and hot plug detect (HPD) signals for DisplayPort applications. The flexibility the HD3SS215 provides by supporting both wide common mode and AC or DC coupled links makes it ideal for many applications.

One typical application would be a mother board that includes two GPUs that need to drive one DisplayPort sink. The GPU is selected by the Dx_SEL pin. Another application is when one source needs to switch between one of two sinks, such as a side connector an a docking station connector. The switching is controlled using the Dx_SEL and AUX_SEL pins. The HD3SS215I operates from a single supply voltage of 3.3 V, over full industrial temperature range –40°C to 85°C, in the ZQE package and 56 pin RTQ package.
