The CorePLL is a dual wideband frequency synthesizer, crafted for ultra-low power consumption, high efficiency, and a compact footprint, ideal for wireless systems such as GSM and LTE. The synthesizer integrates two PLLs, VCOs, and loop filters to enable carrier aggregation across multiple bands, capable of supporting frequencies from 1.333 GHz to 8 GHz.\nThis technology is engineered to minimize power usage with a draw of only 18mA from a 1.35V supply, ensuring optimal operational efficiency. Its integration capabilities include digital calibration tools and lock detection for precise frequency control in dynamic signal environments.\nThe CorePLL is designed to cater to both industrial and automotive applications, thanks to its wide reference signal range and customizable power modes. It keeps in line with 3GPP standards, ensuring broad compatibility across different technological frameworks.
