Abstract
A device for generating synchronous numeric signals, including a reference generating device supplying a reference signal and a first timing signal, both having a reference frequency; and a timed generating device supplying a synchronized signal having the reference frequency. The device further includes a synchronization stage generating a second timing signal having a first controlled frequency correlated to the reference frequency, and phase synchronization pulses having the first frequency and a preset delay programmable with respect to the first timing signal.

A device for generating synchronous numeric signals, comprising:
- reference generating means supplying a reference signal and a first timing signal, both having a reference frequency;
- timed generating means supplying a synchronized signal having said reference frequency;
- and
- synchronization means generating a second timing signal having a first controlled frequency correlated to said reference frequency, and phase synchronization pulses having said reference frequency and a preset delay programmable with respect to said first timing signal.
A method for generating synchronous numeric signals, comprising:
- generating a reference signal and a first timing signal, both having a reference frequency;
- and
- generating, from said first timing signal, a second timing signal having a first controlled frequency correlated to said reference frequency, and phase synchronization pulses having said reference frequency and a preset delay programmable with respect to said first timing signal.
A device for generating synchronous numeric signals, comprising:
- a reference generator operable to supply a reference signal and a first timing signal, both having a reference frequency;
