DS16EV5110_0706 Datasheet, PDF (12/18 Pages) National Semiconductor (TI) – Video Equalizer for DVI, HDMI, and Cat5 Cables

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.

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 5.

HDMI V1.3 APPLICATION
The DS16EV5110 can reliably extend operation to distances
greater than 20 meters of 28 AWG HDMI cable at 2.25 Gbps,
thereby supporting HDMI v1.3 for 1080p HDTV resolution
with 12-bit color depth. Please note that the Electrical Char-
acteristics specified in this document have not been tested for
and are not guaranteed for 2.25 Gbps operation.
DC COUPLED DATA PATHS AND DVI/HDMI
COMPLIANCE
The DS16EV5110 is designed to support TMDS differential
pairs with DC coupled transmission lines. It contains integrat-
ed termination resistors (50Ω), pulled up to VDD at the input
stage, and open collector outputs for DVI / HDMI compliance.
