Description

The PRL-470D is a high speed 50 Ω Line Driver/Level Translator with independently variable output Hi and Lo levels. It has a TTL and a Universal Differential Input. The TTL input has a 50 Ω to ground termination, and Universal Differential Input has a floating 100 Ω termination. The floating differential input accepts LVDS, LVPECL, NECL, RS 422, or any 100 mV_PP minimum differential signal within the window of -2 V to +3 V. The TTL and Universal Differential Input are logically ORed; therefore a Hi level applied to either input can be used as a gate signal. The PRL-470D is an improved version of the earlier Model PRL-470B. The connectors for the universal differential input are SMA, and the connector for the TTL input is BNC. The output connector is SMA.

The output Hi and Lo levels are independently variable from 0 V to +5 V and 0 V to –3 V into 50 Ω, respectively, or +10 V and –6 V into 1 MΩ. The maximum output peak to peak swing is 8 V into 50 Ω, or 16 V into 1 MΩ. The back-terminated 50 Ω output can drive long 50 Ω lines with or without load termination. A Normal/Invert switch provides output logic polarity selection, and an f/2 switch provides square wave output. The 50 Ω TTL input requires less than 1 V for triggering.

The 800 ps rise time output makes the PRL-470D a cost effective TDR source for testing cables. Typical maximum clock rate is 300 MHz @ 3.5 V_PP output and 250 MHz @ 5 V_PP output, well suited for testing logic circuits of different families, amplifiers and many semiconductor devices.

The trigger output generates > 400 mV into 50 Ω or > 800 mV into high impedance, and is back terminated into an AC coupled 50 Ω source. The self-contained 1.3 x 2.9 x 8.1-in module is supplied with a 8.5 V/+17 V AC/DC adapter.
