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. |
