*All measurements are made with outputs terminated into
50 Ω/-2 V, using the PRL-550NQ4X, four-channel ECL Terminators, connected to a
50 Ω input sampling oscilloscope.
Notes:
(1). The output rise and fall times are measured with both the
Q and Q outputs terminated into
50 Ω/-2V. An unused complementary output must be
either terminated into 50 Ω /-2 V or AC coupled into a 50 Ω load; otherwise,
output waveform distortion and rise time degradation will occur. Use the PRL-504
or PRL-508, four and eight channel ECL Termination modules, respectively, for
the 50 Ω/-2V termination. Use the PRL-550ND4X and PRL-550NQ4X, two and four channel ECL Terminators, respectively, for the
50 Ω/-2V termination and for connection of ECL signals to 50 Ω
input oscilloscopes.
(2). fMAX is measured by AC coupling a sine wave to the
D input using the differential input mode (switch up). The differential outputs
are first divided by four, using the PRL-255, and then measured using the
PRL-550NQ4X, four channel ECL Terminators, connected to a sampling 'scope.
