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 coding 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.
