performed before signals are amplified by an LNA. Then SAW filtering is performed again
before signals are input to the BCM47511 for further processing.

Figure 2-9 RF solution for the GPS module of the S10

The BCM47511 chip has the following features:
l
The BCM47511 SoC solution uses an independent new-generation GPS receiver
developed by Broadcom. This GPS receiver integrates the functions of both the GPS and
the GLONASS. The BCM47511 chip is compatible with pins in the popular BCM4751
SoC solution launched by Broadcom. Therefore, customers can quickly upgrade products
to support the GLONASS.
l
The GPS kernel of the BCM47511 chip, based on a host system architecture, splits the
processing function into two parts which are separately implemented by the GPS chip
and the main system CPU. This obviously reduces system costs. In addition, the GPS or
GLONASS software algorithm used on the main system can be customized or optimized
when necessary. After splitting the processing function into two parts, the GPS receiver
of the BCM47511 chip can perform most dense computation tasks, so that the software
on the main system needs only to perform the ultimate calculation.
l
The BCM47511 chip consumes little power and provides an ultra-low-power tracing
mode. It integrates LDO voltage regulators to provide a temperature-compensated crystal
oscillator (TCXO) for the GNSS. The BCM47511 chip can also have LNAs to lower the
total material cost. Broadcom provides GPS location library APIs and GPS protocol
client software, so that designers can make full use of the advanced functions of the
BCM47511 chip.
l
The Bluetooth kernel of the BCM47511 chip is optimized to attain low power
consumption. This kernel also maintains high receiver sensitivity and complies with the
Bluetooth 4.0 specification.
Figure 2-10 shows the functional blocks of the BCM47511 chip.
