APPLICATION INFORMATION
The DS16EV5110 is used to recondition DVI/HDMI video signals 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 maybe used on the Source or Sink
side of the application. The DS16EV5110 ESD protection circuitry will not support the V_OFF specification when
the dowstream device (e.g. DES) is powered ON and the DS16EV5110 is powered OFF. Figure 10 shows the
CML output circuitry and the ESD protection diode (current path). It is also not recommneded to enable the
DS16EV5110 CML outputs without a load attached.

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 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.

DVI 1.0 AND HDMI V1.2a APPLICATIONS
A single DS16EV5110 can be used to implement cable extension 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 WQXGA), a “dual link” TMDS interface is
required. This is easily configured by using two DS16EV5110 devices as shown in Figure 7.
