Abstract

Circuito integrado sintetizador de frecuencias, basado en técnica Phase-Locked Loop (PLL), cuyo objetivo es el control de frecuencias en aquellos sistemas que requieran una conmutación rápida de canal. Este circuito consta de un registro divisor de frecuencias con módulo programable R, para la frecuencia del oscilador de referencia (1); un registro divisor de frecuencias con módulo programable N, para la frecuencia del oscilador controlado por voltaje (2), un módulo de escalado (3), un restador de fase (4), un módulo corrector de fase (5), y un conversor digital/analógico (6).Integrated frequency synthesizer circuit, based on Phase-Locked Loop (PLL) technique, whose objective is frequency control in those systems that require rapid channel switching. This circuit consists of a frequency divider register with programmable module R, for the frequency of the reference oscillator (1); a frequency divider register with programmable module N, for the voltage controlled oscillator frequency (2), a scaling module (3), a phase subtractor (4), a phase corrector module (5), and a converter digital / analog (6).
