CMOS GPS receiver is
industry's most integrated
Chip consumes low power, reduces die size, and
provides low external component count The VS7001 receiver is claimed to be the first
fully integrated GPS receiver based on pure CMOS
technology. Compared to other available GPS
products, the device offers the smallest die
size, provides the lowest external component
count, and consumes the lowest power–27 mW at
2.2 V, making it suitable for battery-operated
products.
The VS7001 GPS receiver provides a fully
integrated, pure CMOS solution. The device eliminates the need for expensive and
bulky SAW IF filters, or passive components,
which other GPS providers use to attenuate image
signal and noise. The VS7001 incorporates a fully
integrated LNA front end, IF section, digital
sampler, and local oscillator synthesizer.
The intended input signal for the device is the
GPS signal at 1.57542 GHz. Specifications
include a voltage range of 2.2 to 3.6 V, an
external LNA gain of 25 dB, a noise figure of 8
dB, a phase noise of –50 dB at 10 kHz, and a
temperature range from –40° to
85°C. Housing is in a 48-pin TQFP package.
