*All measurements are made
with outputs terminated into 50 Ω/VTT,
using the PRL-550NQ4X
or PRL-550PQ4X four channel ECL/PECL Terminators, connected to a
50 Ω input sampling oscilloscope.
Notes:
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.
(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-255N
or PRL-255P, and
then measured using the PRL-550NQ4X
or PRL-550PQ4X, four channel ECL/PECL
Terminators,
connected to a sampling scope.
(3). fMAX is specified for SMA models.
BNC versions are slower.
VTT is nominally
-2.0 V for ECL, +3.0 V for PECL, and +1.3 V for LVPECL. VBB is nominally -1.3 V
for ECL, +3.7 V for PECL, and 2.0 V for LVPECL
