Description

The PRL-430AN is a dual channel, differential/single-ended input NECL receiver module with complementary outputs. It is intended for converting single-ended signals, including GHz sine waves, into differential NECL signals for driving long lines and for receiving differential signals from long lines.

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/-2 V, and, therefore, either one or both inputs can accept AC coupled signals as well. In the single-ended input mode, signals should be connected to the D inputs only. The D inputs are switched internally to V_BB, nominally -1.3 V, and termination resistors R_T for the D input channels are changed to 62 Ω. Complementary outputs of the PRL-430AN are designed for driving 50 Ω loads terminated into -2 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-430AN is housed in a 1.3 x 2.9 x 2.2-in. extruded aluminum enclosure and supplied with a ±8.5 V/1.8 A AC/DC adapter.
