DS16EV51-AEVKD
DVI Extender Demo Kit for Dual or Single Link DVI Cables
General Description
The DS16EV51-AEVKD Dual/Single link DVI Cable Extender Demo Kit provides a complete DVI system extension solution
using two National’s DS16EV5110A’s - Video Equalizers.
Two Molex DVI connectors are used as the input and the output connections for a dual or single link DVI system. This version
of the kit demonstrates both a single link and a dual link DVI system.
The Analog Pins of a typical DVI link (R, G, B, Hsync, and Vsync) are not connected. The DDC signals, Hot Plug, 5V Power
and 5V Ground are directly connected between the DVI connectors, making this demo kit HDCP compliant.
A 3.3V VCC 1-pin header (J4) and a GND 1-pin header (J5) are used for the power supply.
Alternately, an AC/DC power adapter (>800mA) is required for the evaluation kit to provide 5V DC voltage for easy portability.
A 1.8 mm DC Power Jack is used to connect the AC/DC Power Adapter. National’s LP3965, a 3.3V, 1500mA, Fast, Ultra Low
Dropout Linear Regulator, converts the 5V power supply voltage to a 3.3V power supply voltage that powers the
DS16EV5110A’s.
