PROGRAMMABLE ns-PULSE GENERATOR
Rev A2, Page 2/8
DESCRIPTION
Pulse generator iC149 produces pulses with a small
duty cycle in the range of ca. 1 ns up to 64 ns max. in
steps of 0.25 ns at a pulse frequency of 1 MHz. The
pulse width is set by means of two hexadecimal cod-
ing switches in coarse and fine steps.
Alternatively a tunable (P1) oscillator can be used.
The pulses are output both as LVDS and TTL signals.
This module can easily be used with the evaluation
boards HG1D, NZN1D and NZP1D.
