Dual WideBand Frequency Synthesizer with Integrated VCO and Loop Filter

CorePLL is a versatile frequency synthesizer solution with ultra-low power, high performance and small size. Power consumption is only 18mA from 1.35V supply (24mW). CorePLL has high integration level: two fully integrated PLLs with integrated VCOs and loop filters for inter band Carrier Aggregation with two bands. With its 3GPP all band, all feature support, CorePLL fits to various application areas.
