Quick Start Guide
1. Connect 3.3V DC power and ground of the boards to the headers 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 >800 mA)
2. Attach all the applicable cables to the boards.
(a) Attach one pair of CAT5 / CAT6 cable between “JR1” and “JR3” for TMDS links
(b) Attach one pair of CAT5 / CAT6 cable between “JR2” and “JR4” for other control signals
3. Turn on the DVD/Computer and the Monitor/HDTV.

for VO = 1000 mVpp
JP38, JP39
VOD_CRL
Connect JP39 - sets external resistor = 12 k
Ω
for VO = 2000 mVpp
Connect JP27 and JP29 to enable D3
JP27, JP28, JP29
SD / LOCK /EN
Connect JP28 to disable the device outputs
Or, use as SD-EN, LOCK-EN auto control (see datasheet)
JP22
BYPASS
Connect JP22 to VDD to bypass reclock function
Turn the switch to control the EQ boost setting. “0” on the switch refers to the boost
U15
Rotary Switch (EQ)
setting of “0X00”, “7” on the switch refers to the boost setting of “0X07”. (See
datasheet for detailed boost setting information.)
Turn the switch to control the DE setting. “0” = 0 dB, “1” = -3 dB, “2” = -6 dB, “3” = -9
U14
Rotary Switch (DE)
dB, “4”, “5”, “6”, “7” = N/A
Set to “0” in most cases
