Abstract

Frequency synthesiser integrated circuitFrequency synthesiser integrated circuit based on the Phase-Locked Loop (PLL) technique, whose objective is to control the frequency of systems that require quick channel switching.This circuit includes a frequency splitting register with a programmable module R, for the frequency of the reference oscillator (1) a frequency splitting register with a programmable module N, for the frequency of the voltage-controlled oscillator (2), a scaling module (3), a phase subtracter (4), a phase correction module (5), and a digital/analogue converter (6).< IMAGE >.
