Sony Introduces the Industry's First 1-Chip CMOS GPS LSI
SAN DIEGO, Dec. 15 -- 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 -150
dBm, 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 50 mW 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 x1.8 mm, 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 by contacting Sony at
gps@am.sony.com.
