Setup Input Signals
Step 3:
3a: Set the signal generator amplitude to 500 mV.
NOTE:
The signal generator amplitude can vary from 75 mV to 900 mV to produce a 400 mV DUT
output.
3b: Set the signal generator offset to 660 mV (the center of a nominal RSECL output).
NOTE:
The V
IHCMR
(Input High Voltage Common Mode Range) allows the signal generator offset to
vary as long as V
IH
is within the V
IHCMR
range. Refer to the device data sheet for further
information.
3c: Set the generator output for a PRBS data signal, or for a square wave clock signal with
a 50% duty cycle.
Connect Output Signals
Step 4:
4a: Connect the outputs of the device (Q, Q) to the oscilloscope. The oscilloscope
sampling head must have internal 50
termination to ground.
NOTE:
Where a single output is being used, the unconnected output for the pair
must be terminated to
V
TT
through a 50
resistor for best operation. Unused pairs may be left unconnected. Since
V
TT
= 0 V, a standard
50
SMA termination is recommended.
