DESCRIPTION  
The TS3DV621 is  
DVI 1.0  
a 1:2 or 2:1 bi-directional  
DisplayPort 1.1a  
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.  
Bandwidth (-3dB) – 2.2 GHz  
RON – 8 Ω  
CON – 5.6 pF  
VCC Range – 3.0V–3.6 V  
I/O Voltage Range – 0–5 V  
Bit-to-Bit Skew – 6 ps Typical  
Propagation Delay – 40 ps Typical  
Special Features  
Dedicated Enable Logic Supports Hi-Z  
Mode  
IOFF Protection Prevents Current Leakage in  
Powered Down State (VCC = 0 V)  
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.
