PRL-470A High Speed, Line Driver & Level Translator

Mini Modular Instruments > Variable Output Pulse Drivers

The PRL-470A has been replaced by the new PRL-470B. We are no longer taking orders for the PRL-470A. Information contained on these pages is for information only.

Migration information:

• The PRL-470B provides equivalent or superior functionality to the PRL-470A for all specifications except for the amplitude of the trigger output.
• The >4 V (1 MΩ load) trigger output of the PRL-470A has been replaced by the > 2 V (1 MΩ load)  trigger output of the PRL-470B, sufficient for triggering most scopes or TTL inputs. If you require a trigger output >2 V, a PRL-420TD, PRL-414B or PRL-444 line driver may be used to buffer the trigger output. The trigger output is back-matched with 50 Ω for driving un-terminated loads.
• The PRL-470B provides a higher output amplitude (8 Vp-p/16 Vp-p into 50 Ω/1 MΩ), faster rise times (800 ps), and a lower low-level voltage (-3 V/-6 V into 50 Ω/1 MΩ).

Description

The PRL-470A is a high speed 50 Ω Line Driver/Level Translator with independently variable output Hi and Lo levels. It has TTL- and NECL-compatible inputs. The TTL input has a 50 Ω to ground termination, and the single-ended NECL input has a 50 Ω/-2 V termination. The TTL and NECL inputs are logically ORed; therefore a Hi level applied to either input can be used as a gate signal. The PRL-470A is an improved version of the earlier Model PRL-470.

The output Hi and Lo levels are independently variable from 0 V to +5 V and 0 V to -2.5 V into 50 Ω, respectively, or 0 V to +10 V and 0 V to -5 V into 1 MΩ. The maximum output peak to peak swing is 6 V into 50 Ω, or 12 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 850 ps rise time output makes the PRL-470A a cost-effective TDR source for testing cables. Typical maximum clock rate is 300 MHz @3.5 V output and 250 MHz @5 V output, well suited for testing logic circuits of different families, amplifiers and many semiconductor devices.

The 2.2 V 50 Ω TTL trigger output can drive two other PRL-470A's using a 6 dB splitter or other TTL compatible circuits. The self-contained 1.3 x 2.9 x 8-in module is supplied with a ±8.5 V/+17 V AC/DC adapter.

Multiple PRL-470A modules together with other PRL logic function modules, such as Clock Sources, Fanout buffers, Frequency Dividers, Programmable Delay Lines, Logic Level Translators, etc., can be rack-mounted for systems test applications. Consult factory for more information.
