Quick Start
Connect power-supply ground to the GND pin (J35).
Apply +3.3V to the V
CC
1 pin (J1). Due to a small volt-
age drop across the inductor, the true voltage on the
part (measured across C1) is slightly lower than +3.3V.
Adjust the power supply until the voltage across C1
measures +3.3V.
Note:
This step applies power to
channels 1 and 2 only. To supply power to channels 3
and 4, ground and a +3.3V supply must be connected
to J35 (GND) and J1 (V
CC
2).
Cable Driver
1) Connect a differential input signal (600mV
P-P
differ-
ential input amplitude) to one of the cable driver
inputs at SMA edge connectors J9 (DIN1-) and J10
(DIN1+).
2) Connect a 50鈩?oscilloscope to SMA output con-
nectors J7 (DOUT-) and J8 (DOUT+) to observe
the output of the cable driver.
