DS16EV5110A Datasheet, PDF (14/22 Pages) Texas Instruments – DS16EV5110A Video Equalizer (3D+C) for DVI, HDMI Source/Repeater/Sink Applications

In general, the use of multiple equalizers is not recommended
due to accumulation of random jitter.
DVI 1.0 AND HDMI V1.2a APPLICATIONS
A single DS16EV5110A 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 DS16EV5110A devices as shown in
Figure 8.
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.

HDMI V1.3 APPLICATION
The DS16EV5110A can reliably extend operation to dis-
tances greater than 20 meters of 28 AWG HDMI cable at 2.25
Gbps, thereby supporting HDMI v1.3 for 1080p HDTV reso-
lution with 12-bit color depth. Please note that the Electrical
Characteristics specified in this document have not been test-
ed for and are not guaranteed for 2.25 Gbps operation.
DC COUPLED DATA PATHS AND DVI/HDMI
COMPLIANCE
The DS16EV5110A 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 for signal
swing.
