SEMICONDUCTOR INTEGRATED CIRCUIT AND OPERATING METHOD THEREOF |
摘要 |
A semiconductor integrated circuit includes a first wireless access system reception unit including a first analog reception unit and a first digital reception unit, a voltage-controlled oscillator, a phase locked loop, and a digital interface. The first analog reception unit comprises a first reception mixer for down-converting an RF reception signal into a first analog reception signal and a first analog-digital converter for converting the first analog reception signal into a first digital reception signal. The first wireless access system reception unit, the voltage-controlled oscillator, and the phase locked loop enable switching from a reception operation for a first RF reception signal of a first system to a reception operation for a second RF reception signal of a second system. |
