The BCM4750 is a single-chip, single-die GPS receiver IC fabricated on 90 nm RFCMOS technology. The BCM4750 integrates a high-performance baseband section with a low-noise CMOS radio front end. It is designed to interface with host processors in mobile phones, PDAs, Personal Navigation Devices (PNDs), and MP3 players. The BCM4750 is a host-based GPS IC that delivers the highest positioning performance yet uses the smallest PCB area in the market today.
Broadcom provides a software library that realizes the GPS navigation solution in the host using minimum resources and with no real time requirements. The BCM4750 uses a patent pending innovative RF design that improves both current consumption and LNA linearity as well as allowing for a minimum number of external components used.
