DS16EV51-AEVKH
HDMI Extender Demo Kit for HDMI Cables
General Description
The DS16EV51-AEVKH HDMI Cable Extender Demo Kit provides a complete HDMI system extension solution using
National’s DS16EV5110A - a Video Equalizer for HDMI cables.
Two HDMI female connectors are used as the input and the output connections for a HDMI system.
The DDC signals, Hot Plug, 5V Power and 5V Ground are directly connected between the HDMI 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 1.8mm 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.

Function
The LED turns on when 5V DC applies
The LED turns on when the DS16EV5110A does not detect clock signal
Optional DC Power Jack for 1.5 mm Adaptor Plug
3.3V VCC power supply
GND
Optional SMBus Control. See Datasheet.
Optional SMBus Control. See Datasheet
Optional SMBus access. See Datasheet
Connect “LED” and “SD” to enable D2 function.
Connect “SD” and “EN” to enable look back control function. When the clock
signal is not detected, the DS16EV5110A sets to power down mode.
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.
