Clock Configuration
Half-Rate or Full-Rate Clock
A half-rate clock from 4 to 16.25GHz for data rates of 8 to 32.5Gbps may be used.
A full-rate clock from 1 to 17GHz for data rates of 1 to 17Gbps may be used.
Apply a clock to Clock In single-ended or differentially. It is recommended, if possible, to use a
differential clock input. Inputs are AC coupled inside the unit. If using only a single-ended input, 50Ohms
terminate the unused input. Single-ended input amplitude can range from 100mV to a maximum of 500mV
peak to peak.
For Half-Rate Clock
The clock input should have a 50±1% duty cycle. Move the Clock Multiplier slider from the top
down until the Output Duty Cycle ~= Input Duty Cycle indicator. Usually just move the mouse
scroll wheel one click at a time, and wait for it to indicate the update. It is necessary to wait a
couple seconds after moving the slider to get a new reading on the Input/Output Duty Cycle
indicator. Repeat this step anytime the clock frequency is changed.
Note: Be aware that positions of Fine Adjustment and Coarse Adjustment controls may affect
the output clock duty cycle which may require the Clock Multiplier to be adjusted again.
For Full-Rate Clock
Move the Clock Multiplier slide bar to the bottom (-2.2) to turn off.
