TS3DV621

The TS3DV621 is a 1:2 or 2:1 bi-directional multiplexer/demultiplexer with a integrated 4 side-band control channel (DDC, AUX, CEC, or HPD) signal switcher. Operating from a 3 to 3.6V supply, the TS3DV621 offers low and flat ON-state resistance as well as low I/O capacitance, which allows the TS3DV621 to achieve a typical bandwidth of 2.2 GHz. The device provides the high bandwidth necessary for HDMI, DVI, and DisplayPort applications. The TS3DV621 expands the high-speed physical link interface from a single HDMI port to two HDMI ports (A or B port) or vise-versa. It can also be used for DisplayPort (DP) source/sink applications. The integrated side-band control channels allow 5V signals to pass through, making the TS3DV621 suitable for HDMI applications.

The most common application for the TS3DV621 is the sink application. In this case, there are two possible sources (DVD, set-top box, or game console) that are routed to one receiver. The unselected port is in the high-impedance mode, such that the receiver receives information from only one source. HDCP encryption is passed through the switch for the receiver to decode.
