2484P-200 - Programable Pulse-Video Delay Line

General Description

This delay line can be used in pulse and analogue mode and provides fine adjustment of circuit path delay, in 5nS increments from zero to a maximum of 155nS. When used in digital circuitry it's low losses and accurate timing allow precise correction to be made. In the analogue mode it's low distortion factor allows faithful transmission of time and coding pulses, while video signals with a bandwidth upto 10MHz may be handled with appropriate equalisers. (It does not contain internal equalisers).

Presentation is suitable for through-hole PCB mounting, with pins on a standard 0.1" (2.540mm) pitch matrix.

Other variations on the 2484P-200 are also available with different delay values and frequency ranges.
