Description

The PRL-460PND is a dual channel PECL to NECL Logic Level Translator. Each unit can receive either single ended or differential input signals, to be selected by a switch. The outputs of the PRL-460PND translators are designed for driving 50 Ω loads terminated to -2 V. These high speed translators facilitate testing and integration of high speed digital communications circuits and systems, where conversion of signals between the PECL to NECL logic families is often required.

The PRL-460PND input is designed to interface with PECL circuits operating with a +5 V supply. In the differential input mode, both inputs D and D of the PRL-460PND are terminated into 50 Ω/+3 V. In this mode, either one or both inputs can accept AC coupled signals as well. In the single input mode, signals should be connected to the D inputs only. Inputs D are switched internally to VBB, nominally +3.7 V, and termination resistors RT for the D input channels are changed to 62 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.
