Broadcom's single chip GPS receiver supports the new QZSS

Broadcom has announced that the BCM4751, a integrated monolithic GPS receiver for mobile devices, supports the new Quasi-Zenith Satellite System (QZSS) launched by Japan earlier this month. The BCM4751 solution has built-in support for QZSS and also supports additional satellite constellations including the Satellite Based Augmentation System (SBAS). Broadcom says that this solution will provide an improved urban canyon navigation in major cities such as Tokyo

The Broadcom BCM4751 is a single-chip GPS receiver used for tracking and navigation, primarily in mobile devices. This GPS reciever is built using a 65 nanometer CMOS design featuring a highly integrated radio frequency (RF) and baseband processor with a low power consumption. The BCM4751 has PCB footprint of 30 mm(2) including band-pass filter, TCXO and passives. The chip supports GPS, SBAS and QZSS satellites at L1 frequency band. It also features
integrated power management allowing direct connection to the battery.

The BCM4751 supports the new set of pseudo random number (PRN) codes required in QZSS satellites. This GPS receiver has a parallel, hardware correlator architecture that enable fast signal searches, accurate real-time navigation, improved tracking sensitivity and low average power consumption. Broadcom is working closely with the Japan Aerospace Exploration Agency (JAXA) to test reception of live QZSS signals and codes.

"JAXA innovations are driving improved user experience of advanced navigation products. For that reason, JAXA is excited to work with Broadcom to be among the first companies to demonstrate the significant performance benefits of adding the Quasi-Zenith Satellite System (QZSS), including aiding in urban canyon navigation, providing a straighter, more accurate and reliable navigation solution, as well as position fixes in more areas." said Koji Terata, Project Manager QZSS, JAXA.

"We are pleased to announce our support of Japan's QZSS satellite system which will improve the accuracy and availability of satellite navigation services. The BCM4751 already sets new standards in performance and low power consumption with state-of-the-art sensitivity and navigation performance and our support for QZSS only accelerates our customers' ability to realize the additional performance benefits provided by this exciting new system." said Scott Pomerantz, Vice President & General Manager, Broadcom's GPS line of business.

Package: Wafer level ball grid array (WLBGA) and fine pitch ball grid array (FPBGA).
