CSR has introduced the SiRFstarIV GSD4e GPS location processor,
a new member of the SiRFstarIV architecture, with a built-in
CPU and innovations such as SiRFGeoRecov technology to ensure
continuous location awareness of digital cameras, portable
game consoles, wearable platforms and other consumer devices,
without loading the host processor.
The GSD4e combines RF receiver and integrated LNA, baseband
circuitry, switcher and low-current LDOs on a single chip,
and requires five to six external passive components and
a single SAW to provide a complete solution that occupies
less than 25 square millimeters, including switcher parts.
"Adding the GSD4e to our SiRFstarIV portfolio gives
our customers the choice of both plug-in and host-based
implementations of our breakthrough location awareness technology
for greater flexibility in creating a variety of geo-aware
mobile devices, furthering our vision of making location
truly a part of everyday life." said Kanwar Chadha,
chief marketing officer for CSR and founder of SiRF. "And
because it has a built-in processor, the GSD4e makes it
easy to quickly integrate location awareness into existing
platforms, enables development of innovative modules and
products with customizable differentiation and provides
our extensive SiRFstarIII customer community with a seamless
upgrade path."
The GSD4e employs motion-sensing algorithms to ensure accurate
positioning even when standing still. And the GSD4e is a
complete position-velocity-time (PVT) solution for location-aware
consumer devices for products such as smartphones, GPS modules,
multi-radio modules and similar applications.
The GSD4e consumes 8 mW in 1-Hz TricklePower mode, and
can maintain hot-start conditions continuously in SiRFaware
mode while drawing 50-400 µA. Its enhanced SiRFNavPlus
navigation engine ensures better car and pedestrian navigation
in tough urban canyon and dense foliage environments.
The SiRFstarIV architecture core features GPS location
engine, smart location sensor interface, adaptive micro-power
manager and active jammer remover.
The GSD4e also supports satellite-based augmentation systems,
including WAAS, EGNOS, MSAS and GAGAN. "The ROM version
of the GSD4e GPS engine has the advantage of being an extremely
cost-effective, small and low-power solution with complete
location capability for easy integration into space and
processing resource constrained consumer devices,"
said Sunil Gopinath, senior product marketing manager for
CSR's audio and consumer business unit. "The flash
version gives customers access to extra throughput of the
CPU, more flexibility to customize and quick access to new,
innovative algorithms from CSR, while our development tools
enable them to create custom software to run on the GSD4e
processor and flash memory, and thus add their own innovations."
Package:
The ROM version measures a 3.5 mm × 3.2 mm, and comes
in a 42-ball, 0.5-mm pitch WLCSP package
The flash version measures 5 mm × 7.2 mm, and comes
in a 103-ball, 0.5-mm pitch BGA package
Availability:
The CSR SiRFstarIV GSD4e single-chip GPS engine with external
flash memory is available in sample quantities this month.
The ROM version will be available later this quarter. Production
quantities are scheduled for the first quarter of 2010.
