SONY INTRODUCES THE INDUSTRY'S FIRST 1-CHIP CMOS GPS LSI
SAN DIEGO, Calif., Dec. 15, 2003 -- Sony Electronics today announced the industry's first single-chip CMOS
Global Positioning System (GPS) LSI that incorporates a built-in RF circuit in an ultra-miniature design.
Designed independently by Sony, the CXD2951 incorporates Sony's advanced RFCMOS block signal processing
architecture to enable high sensitivity, minimal power consumption and high-performance. The new LSI
configuration is ideal for a wide range of location-based applications such as automotive, cellular
handsets, handheld navigation, fleet management, and mobile computing devices.
"We are very excited to bring a technology that was once mainly used in car navigation systems to a
variety of portable electronics devices that we use in our daily lives," said Aki Hasegawa, president of Sony
Electronics' Component Solutions Business Division. "The new Sony GPS LSI achieves improved sensitivity and faster
processing while consuming less power, making it ideal for mobile computing products."
Capable of stand-alone and network assisted signal detection of up to -150dBm, the new LSI achieves high
sensitivity that enables even indoor reception of GPS satellite signals. Combining hot start positioning time of
two to six seconds and power as low as 50mW during tracking, the device achieves optimal power management and high
performance.
In addition, the new GPS LSI incorporates an external bus, GPIO, UART, and built-in RTC circuits, thus integrating
all necessary GPS functions in a single CMOS chip for easy and cost-effective implementation into a GPS receiver.
The CXD2951 features a simple serial interface connection and supports a wide range of TCXO frequencies,
including those used in GSM, W-CDMA and AMPS cellular applications. The LSI comes in three different packages
— GA, GL and GH — to meet customers' size and mounting requirements.
Using the CXD2951, Sony has developed a miniature GPS module with a footprint of 14 x 23 x 1.8mm,
passive-antenna integrated GPS module, as well as an automotive-grade module conforming to QS9000/TS16949. All are
designed to meet a wide range of applications and user requirements. With this advanced module technology, Sony
continues to strive for significant cost savings, size reduction, and higher performance.
Availability
The first mass production shipments of the CXD2951 chips will start this month. Samples are available upon request
