Description

The PRL-430LP is a dual channel, differential/ single-ended input LVPECL receiver module with complementary outputs. It is intended for converting single-ended signals, including GHz sine waves, into differential LVPECL 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/+1.3 V, and, therefore, 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. The D inputs are switched internally to V_BB, nominally +2.0 V, and termination resistors R_T for the D input channels are changed to 62 Ω. Complementary outputs of the PRL-430LP 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-430LP complementary outputs must be used together for driving differential LVPECL inputs only, because the reduced output logic swing of 400 mV_PP (for short circuit protection reasons) is not logic level compatible with some single-ended LVPECL inputs.

The PRL-430LP 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.

*All measurements are made with outputs terminated into 50 Ω/V_TT, using the PRL-550LPQ4X four channel LVPECL Terminator, connected to a 50 Ω input sampling oscilloscope.

Notes:

(1). The output rise and fall times are measured with both the Q and Q outputs terminated into 50 Ω/V_TT. An unused complementary output must be either terminated into 50 Ω/V_TT or AC coupled into a 50 Ω; otherwise, output waveform distortion and rise time degradation will occur. Use the PRL-550LPQ4X four channel LVPECL Terminator for the 50 Ω/+1.3 V termination and for connection of LVPECL signals to 50 Ω input oscilloscopes.

(2). f_MAX is measured by AC coupling a sine wave to the D input using the differential input mode (switch up). The differential outputs are first divided by four, using the PRL-255LP, and then measured using the PRL-550LPQ4X, four channel LVPECL Terminator, connected to a sampling scope.
