ELECTRONIC CIRCUITRY

H03L

AUTOMATIC CONTROL, STARTING, SYNCHRONISATION OR STABILISATION OF GENERATORS OF ELECTRONIC OSCILLATIONS OR PULSES

7/00

Automatic control of frequency or phase; Synchronisation

H03L7/06

using a reference signal applied to a frequency- or phase-locked loop

H03L7/16

Indirect frequency synthesis, i.e. generating a desired one of a number of predetermined frequencies using a frequency- or phase-locked loop

H03L7/18

using a frequency divider or counter in the loop

H03L7/183

a time difference being used for locking the loop, the counter counting between fixed numbers or the frequency divider dividing by a fixed number

H03L7/195

in which the counter of the loop counts between two different non zero numbers, e.g. for generating an offset frequency
