APPLICATION INFORMATION
SNLS301C – JULY 2008 – REVISED APRIL 2013
The DS16EV5110A is used to recondition DVI/HDMI video signals or differential signals with similar
characteristics for signal loss and degradation due to transmission through a length of shielded or unshielded
cable. The DS16EV5110A maybe used on the Source or Sink side of the application or as a Repeater (Sink and
Source).
In the Source Side application the DS16EV5110A is located near the Serializer and conditions the signal for
losses due to internal cabling or FR4 losses (backplane). The signal is then re-driven at full amplitude and
reduced jitter over the external cable interconnect.

In the Sink Side application the DS16EV5110A is located next to the Deserializer and post-conditions the signal
for losses incurred over the cable interconnect.

The DS16EV5110A may be used in repeater type application as shown in Figure 7 . The cable on the output of
the repeater tends to be shorter and may be a dongle type application. The input of the repeater recovers the
signal after transmission over a long cable interconnect.

In general, the use of multiple equalizers is not recommended due to accumulation of random jitter.
