Description

The PRL-431N, PRL-431P, and PRL-431LP are a 1:2 Differential Fanout ECL, PECL and LVPECL Buffer modules, respectively. They are essential lab tools for applications where it is necessary to drive two different loads from a source of single-ended or differential ECL, PECL or LVPECL signals. They can also be used for converting GHz sine wave signals into differential ECL, PECL or LVPECL signals.

A switch selects either single-ended or differential inputs, as shown in Fig. 1. In the differential input mode, both inputs D and D are terminated internally into 50 Ω/V_TT*, and, therefore, either one or both inputs can accept AC-coupled signals as well. In the single input mode, signal should be connected to the D input only. The D input is switched internally to V_BB**, and termination resistor R_T for the D input is changed to 62 Ω. Complementary outputs of the PRL-431N are designed for driving 50 Ω loads terminated into -2 V. Complementary outputs of the PRL-431P are designed for driving 50 Ω loads terminated into +3 V. Complementary outputs of the PRL-431LP are designed for driving 50 Ω loads terminated into +1.3 V. With internal pull-down resistors, these outputs can also be AC-coupled for driving 50 Ω loads terminated to ground or to other voltages.

The PRL-431N, PRL-431P, and PRL-431LP are each housed in a 1.3 x 2.9 x 2.2-in. extruded aluminum enclosure and supplied with a ±8.5 V/1.4 A AC/DC Adapter.

V_TT is nominally -2.0 V for ECL, +3.0 V for PECL, and +1.3 V for LVPECL. V_BB is nominally -1.3 V for ECL, +3.7 V for PECL, and 2.0 V for LVPECL
