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.

Quick Start Guide:
1. Connect 3.3V DC power to J4 and ground to J5 from the power supply.
Or, plug the AC/DC power adapter to the DC power Jack
AC/DC power adapter requirement: Output DC 4V~6V, Output current > 800mA
2. Attach two DVI cables to the DVI Input and Output Connectors
3. Turn on the DVD/Computer and the Monitor/HDTV.
Adjustment and Control Description
Component Name Function
D4 PWR The LED turns on when 5V DC applied
D5 SD The LED turns on when the DS16EV5110 does not detect clock signal
J47 5V DC Optional DC Power Jack for 1.8 mm Adaptor Plug
J4 3.3V 3.3V VCC power supply
J5 GND GND
J10 FEB and GND Optional SMBus control of U14 (See Datasheet)
J9 CS and VDD Optional SMBus control of U14 (See Datasheet)
J7 FEB and GND Optional SMBus control of U13 (See Datasheet)
J8 CS and VDD Optional SMBus control of U13 (See Datasheet)
J11, J12 SDA, SDC and GND Optional SMBus access (See Datasheet)
J15 Loop Back Control
Connect “LED” and “SD” to enable D5 function.
Connect “SD” and “EN” to enable look back control function. When the clock
signal is not detected, the DS16EV5110A enters power down mode.
U3 Rotary Switch
Turn the switch to control the EQ boost setting. “0” on the switch refers to the
boost setting of “0X00”, “7” on the switch refers to the boost setting of “0X07”.
See datasheet for detail Boost setting information.

Layout Considerations
•Keep the clock and data transmission lines as short as possible with controlled 50 ohm single-ended impedance. Or,
use differentially coupled traces with 100 ohm impedance.
•Avoid using vias on the clock and data transmission lines on the input side of the DS16EV5110A.
•Place power supply decoupling capacitors close to the VCC pins.
