SPECIFICATIONS
Unless otherwise specified, dynamic measurements are made with all outputs terminated into 50 Ω/V
ECL outputs and 0 V for TTL outputs.
(1) If the switch is set to the center position (0 V threshold) a non-driven channel will oscillate and induce jitter in the driven channel. Connect any output to any
input to stop the oscillation.
(2) 20%-80% for ECL outputs, 10%-90% for TTL outputs. For the PRL-350ECL, an unused complementary output must be either terminated into 50 Ω/V
AC coupled into a 50 Ω load; otherwise, output waveform distortion and rise time degradation will occur. Use the PRL-ACT-50, Dual Channel AC-Coupled
50 Ω Termination, for terminating unused complementary outputs. Use the PRL-550NQ/PQ4X, Four Channel NECL/PECL Terminators, respectively, for the
50 Ω/V
0.1 µf DC block or the PRL-ACX-12dB, 12 dB AC-coupled attenuator may be used to connect the NECL/PECL outputs to 50 Ω input instruments.
For the PRL-350TTL, very slight output waveform distortion and rise time degradation will occur when an unused complementary output is not terminated. For
optimum performance, however, all outputs should be terminated.
(3) In order to reduce jitter near f
(4) Although the PRL-350ECL typically operates up to 2 GHz, the internal device is specified at 1 GHz by the device manufacturer; therefore the guaranteed
f

is 1 GHz.
