Pulse Research Lab (PRL) announces the PRL-260ANT Programmable TTL/NECL Frequency Divider. This self-contained divider pod accepts an input frequency f from DC to 1 GHz and outputs divided TTL and ECL clock signals with ratios from f/2 to f/4096. 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 PRL-260ANT will accept TTL and ECL clock signals as well as AC-coupled PECL, LVPECL or sinewave signals. The input frequency f is first divided down to f/n, where 2 < =n< =256. The f/n signal is then further divided by 1, 2, 4 or 8 for the first-phase ECL and TTL outputs and by 2, 4, 8 or 16 for the second-phase ECL output. The device is appropriate for applications where a frequency divider or prescalar is needed for triggering or down-sampling, and the multiple logic inputs and outputs make it extremely useful in mixed-logic environments.
