Receiver and Line Driver suit long-distance applications.

Press Release Summary:

Universal Differential Receivers and Line Drivers in PRL 425 Series are compact, self-contained buffer pods that can receive any differential signal with min amplitude of 100 mV and CMR between -2.4 and +4 V. Long line drivers have differential TTL and RS-422 outputs that can run up to 300 MHz and NECL outputs up to 1.8 GHz. PRL-425 Universal Differential Receiver suits line-driver applications where single-function instrument pod is needed to receive/transmit signals.

Pulse Research Lab Introduces New Universal Differential Receiver and Line Driver

October 20, 2005 - Torrance, CA - Pulse Research Lab (PRL) announces the innovative PRL 425 Series Universal Differential Receivers and Line Drivers. These compact, self-contained buffer pods are long line drivers that can receive any differential signal with a minimum amplitude of 100 mV and a common-mode range (CMR) between -2.4 V to +4 V. The differential TTL and RS-422 outputs can run up to 300 MHz, and the NECL outputs up to 1.8 GHz. The new, ready-to use PRL-425 Series can translate and/or buffer signals from satellite receivers, optical transceivers, military equipment, and telecommunications equipment. The PRL-425 series of multipurpose modules is available with Triax I/O connectors or differential SMA inputs and floating 100 Ohm differential input impedance, suitable for receiving differential LVDS, LVPECL, LVTTL/CMOS, NECL, PECL, LVPECL, RS-422, or TTL signals.

Pulse Research Lab's three individual models offer TTL, NECL, or RS-422 outputs, respectively. The PRL 425T has 50 ohm back-terminated TTL outputs that can drive long lines with or without 50 ohm terminations. With 50 ohm load terminations, the TTL outputs can drive 100 ft. of 50 ohm cables at clock rates greater than 100 MHz. The NECL outputs of the PRL-425N can drive 50 Ohm loads terminated into -2V or AC-coupled 50 Ohm loads up to 1.8 GHz. The TTL and NECL outputs are SMA and can be used differentially or single-ended. The outputs of the PRL-425RS will drive a standard RS-422 differential input up to 600 MHz, and are also available with SMA or Triax I/O connectors.

The PRL-425 Universal Differential Receiver is ideal for line-driver applications where a single-function instrument pod is needed to receive and/or transmit differential signals over long distances. PRL's wide range of line drivers and level translator products, paired with the innovative PRL-425 Series, enables the translation, distribution, and transmission of mixed logic signals commonly required in system integration, military/aerospace, and test applications.

Each unit includes a 120/220 VAC adapter and SMA or Triax signal connectors for ready-to-use convenience on the bench, in a system, or in your OEM application. The compact (1.3 in. x 2.9 in. x 3.9 in.) extruded aluminum housing is suitable for mounting with the optional brackets, and several units can share a single AC adapter using PRL voltage distribution modules.

Pulse Research Lab, established in 1990, provides signal buffering & translation modules for digital design, integration and testing. The company offers high-performance, affordable Basic Lab Tools and prototyping tools to professional electrical engineers, scientists, and technicians. Founder, David Kan, states, "PRL's charter has been to listen to our customers' problems and provide solutions. We've proudly and successfully been doing this for over fifteen years."
