Four-channel line driver can receive signals from devices with low drive current, such as sensors, PC-based digital I/O cards, camera triggers, recorders, and laboratory equipment
Pulse Research Lab (PRL) announces the PRL444 four channel, high input impedance, 50 ohm TTL line driver.
This compact, self-contained buffer pod drives four TTL/CMOS signals into 50 ohm loads.
With a 10k ohm input impedance, the new, ready-to use PRL-444 can receive signals from devices with low drive current, such as sensors, PC-based digital I/O cards, satellite receivers, optical transceivers, camera triggers, recorders, and laboratory equipment with TTL/CMOS outputs.
Each input has a 10k ohm pulled up to 2.5V so it can also be driven by open-collector devices.
The 50 ohm back-terminated outputs of the PRL-444 can drive long lines with or without 50 ohm terminations.
With 50 ohm load terminations, all outputs can drive 30m of 50 ohm cables at clock rates greater than 60MHz.
The PRL-444 is said to be ideal for applications where a single-function instrument pod is needed to drive multiple TTL/CMOS outputs into 50 ohm loads.
Small enough to fit anywhere on a test bench, it can often replace the need for bulky, expensive pulse generators at a fraction of the cost.
The line driver works extremely well for high speed digital communications, test and measurement, system integration, hi/lo logic level generation, and basic lab use.
The unit includes an AC adapter and BNC or SMA signal connectors for ready-to-use convenience on the bench or in a system.
The extruded aluminium housing is suitable for mounting with the optional brackets, and up to four units can share a single AC adapter using PRL voltage distribution modules.
