Frequency divider spans four decades

The PRL 230 is a four-decade TTL frequency divider pod that accepts TTL clock signals from DC to 100MHz and generates f/10, f/100, f/1,000 and f/10,000 divided outputs.

New from Pulse Research Lab (PRL), the PRL 230 is a four-decade TTL frequency divider. This self-contained frequency divider pod accepts TTL clock signals from DC to 100MHz and generates f/10, f/100, f/1,000 and f/10,000 divided outputs. All divided outputs are synchronous with the input frequency and can be used for triggering data acquisition systems, pattern generators, oscilloscopes, and networking/telecommunications devices.

The compact PRL 230 can easily be cascaded with additional PRL 230 units (or other PRL frequency divider pods) for even higher division ratios.

The TTL input has a switchable 50/500ohm input impedance, and can toggle up to 100MHz.

The four divided TTL outputs are back-matched and can drive terminated or unterminated loads.

Each output delivers greater than 2.2V into a 50ohm load.

All outputs, except the f/10 channel, have square-wave outputs (50% duty cycle).

For the f/10 channel, the output pulsewidth is equal to the period (1/f) of the input signal.

The PRL 230 is ideally suited for applications that require very large division ratios, and the square wave outputs are useful for testing highpass and lowpass filters.

Applications for the PRL 230 include data acquisition, test, measurement, R and D and system integration.

The unit includes an AC adapter and BNC or SMA connectors for ready-to-use convenience on the bench or in a system.

The extruded aluminium housing can be easily mounted with the optional brackets, and up to four units can share a single AC adapter using PRL voltage distribution modules.
