Step 1: Connect Power
1a: Two power levels must be provided to the board for V CC ,
V EE , and GND via the surface mount clips.

Step 2: Connect Inputs
For Differential Mode (3.3 V and 2.5 V operation)
2a: Connect the differential output of the generator to the
differential input of the device (CLK and CLK).
3.3 V Setup
V CC = 0 V
GND = 0 V
V EE = ? 3.3 V
2.5 V Setup
V CC = 0 V
GND = 0 V
V EE = ? 2.5 V
