Application Information
The DS16EV5110 is used to recondition DVI/HDMI video sig-
nals or differential signals with similar characteristics after
signal loss and degradation due to transmission through a
length of shielded or unshielded cable. It is intended to be
used on the Sink-side of the video link. The DS16EV5110A
The DS16EV5110 may also be used in certain Source-side
application with certain restrictions. The DS16EV5110 CML
outputs will not meet the VOFF parameter required by the
HDMI Compliance Test Specification (v1.3b) when the
DS16EV5110 is powered off and the sink device is powered
DVI 1.0 AND HDMI V1.2a APPLICATIONS
A single DS16EV5110 can be used to implement cable ex-
tension solutions with various resolutions and screen refresh
rates. The range of digital serial rates supported is between
250 Mbps and 1.65 Gbps. For applications requiring ultra-
high resolution for DVI applications (e.g., QXGA and WQX-
GA), a “dual link” TMDS interface is required. This is easily
configured by using two DS16EV5110 devices as shown in
Figure 7.

diode (current path). It is also not recommneded to enable the

on. A current path will be enabled through the ESD protection
diode (see Figure 10). If full compliance is not required, the
DS16EV5110 may be used in repeater type application as
shown in Figure 6 .
Note the recommended connections between LVCMOS con-
trol pins. This provides the Automatic Enable feature for both
devices based on the one active clock channel. In many ap-
plications the SMBus is not required (device is pin controlled),
for this application simply leave the three SMBus pins open.
SDC and SDA are internally pulled High, and CS is internally
pulled Low, thus the SMBus is in the disabled state.
