Description

The PRL-350ECL and PRL-350TTL are ready-to-use, high speed dual-channel comparator modules. The PRL-350ECL has a maximum clock frequency in excess of 1 GHz and has complementary ECL outputs designed for driving 50 Ω transmission lines terminated to 50 Ω/-2 V. The PRL-350TTL has a maximum clock frequency in excess of 300 MHz and has complementary TTL outputs designed for driving 50 Ω transmission lines with or without 50 Ω load terminations. The PRL-350P is the PECL version, and the PRL-350LP is the LVPECL version.

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.

These high speed comparators are Mini Modular Instruments ™ that can be used as peak detectors, threshold detectors, sine wave to square wave converters, window comparators or differential line receivers, etc. Typical minimum input voltage required at 300 MHz is 10 mV p-p. into 50 Ω.

Each unit is supplied with a ±8.5 V AC/DC Adapter and housed in an attractive 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_MAX is 1 GHz.
