FEATURES
DESCRIPTION
The PRL-350ECL and PRL-350TTL are ready-to-use, high-speed dual-channel comparator modules. The PRL-350ECL has a
typical maximum clock frequency in excess of 2 GHz
transmission lines terminated to 50 Ω/-2 V. The PRL-350TTL has a typical maximum clock frequency in excess of 250 MHz
and has complementary TTL outputs designed for driving 50 Ω transmission lines with or without 50 Ω load terminations.
Both models have DC coupled 50 Ω inputs and outputs. Input threshold voltage can be selected either from a set of preset values
of +50 mV, 0 V or –50 mV using a common three-position switch, or varied independently in each channel by applying a DC
voltage to one of the two inputs. Input Common Mode Range is –2.0 V to +3.0 V. Models with -NIM suffix, such as
PRL-350TTL-NIM, have ±400 mV or 0 V preset input threshold voltage. The -400 mV threshold setting is intended for NIM
input signals. The 0V threshold setting is intended for signals with zero crossings, such as a sinewave or AC-coupled square
wave, etc.
These high-speed comparators are Mini Modular Instruments™ that can be used as peak detectors, threshold detectors,
sinewave-to-square wave converters, window comparators or differential line receivers, etc. Typical minimum input voltage of
10 mV
the non-driven input be terminated into 50 Ω when the input frequency is near f
Each unit is supplied with a ±8.5 V AC/DC Adapter and housed in a 1.3 x 2.9 x 3.9-in. extruded aluminum enclosure.
* 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.

... DC block or the PRL-ACX-12dB 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. ...
