Note the recommended connections between LVCMOS control pins. This provides the Automatic Enable feature
for both devices based on the one active clock channel. In many applications 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 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 Characteristics specified in this document have not been tested for and are not ensured 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
integrated termination resistors (50Ω), pulled up to VDD at the input stage, and open collector outputs for DVI /
HDMI for signal swing.
CABLE SELECTION
At higher frequencies, longer cable lengths produce greater losses due to the skin effect. The quality of the cable
with respect to conductor wire gauge and shielding heavily influences performance. Thicker conductors have
lower signal degradation per unit length. In nearly all applications, the DS16EV5110 equalization can be set to
0x04, and equalize up to 22 dB skin effect loss for all input cable configurations at all data rates, without
degrading signal integrity.
