Notes:
All dynamic measurements are made with outputs terminated into 50 Ω/VTT, using the
PRL-550 Series, four channel ECL/PECL/LVPECL Terminators, connected to a 50 Ω input sampling oscilloscope.
The output rise and fall times are measured with with all inputs terminated into 50 Ω/VTT. For best performance all outputs should be
terminated into 50 Ω/VTT or else AC- coupled into 50 Ω
loads. If a single output is used, its complement must be terminated; otherwise
output waveform distortion will occur. If one pair of complementary outputs is
used, the other complementary pair may remain unterminated.
Use the PRL-550 Series,
four channel ECL/PECL/LVPECL
Terminators, for the 50 Ω/VTT termination and for
connection of ECL/PECL/LVPECL signals to 50 Ω input oscilloscopes. The
PRL-ACT-50, Dual Channel AC-Coupled 50 Ω
Terminator,
may also be used to provide the 50 Ω/VTT
termination. If preservation of DC levels is not required, then the PRL-SC-104, 0.1
µf DC block or the PRL-ACX-12dB, 12 dB AC-coupled attenuator, may be used to connect the NECL/PECL/LVPECL
outputs to 50 Ω input instruments.
fMAX is measured using differential inputs only. The outputs are
first divided by four, using the PRL-255N/P
ECL/PECL Frequency Divider, and then measured using the PRL-550
Series,
four channel ECL/PECL/LVPECL Terminator, connected to a sampling 'scope.
When the unit is driven by an AC-coupled sine wave signal
in the differential input mode, the signal swing is symmetric with respect to VTT. The peak-to peak swing of the input signal should not exceed these Common
Mode limits.
