DESCRIPTION
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.
