2.2 Receiver architecture
The functional architecture of the Jupiter
2.3 Major components of the Jupiter
SAW filter (1.575 GHz): This filters the GPS signal and removes unwanted signals caused by external influences that would
corrupt the operation of the receiver. The filtered signal is fed to the RF input of GSC3f chipset for further processing. The filter
has a bandwidth of 2 MHz.
VDD_RTC: This supplies the RTC core and system FSM (Finite State Machine). It also supplies the BBRAM that maintains
system and user variables.
GS3f/LPx RTC crystal controls/GPIO (General Purpose Input Output): This single chip GPS device includes an
integrated Baseband, RF section and integrated Flash which stores software, long term and user configuration data.
LNA (Low Noise Amplifier): This amplifies the GPS signal and provides enough gain for the receiver to use a passive
antenna. A very low noise design is utilised to provide maximum sensitivity.
VDD_BB: The primary supply voltage for the Digital and DSP section its range is 2.7V to 3.0V.
VCC_RF: The primary supply voltage for the RF section and its range is 2.7V to 3.0V.
RTC Clock interface: This supports a low cost RTC crystal or a shared 32KHz clock.
SRESET (NSRESET): This is the system Reset input for POR and Reset control.
Controls: These signals allow Power Save modes and correct GPS shutdown. They also allow an ON_PFF pulse to be used for
controlled shut downs and start ups. Note that a serial message can also be used to shut down the GPS.
UART ports: These are the primary serial communications ports for NMEA or SiRF Binary protocols.
SPI (not shown): This is a high speed serial communication port used for DR.
TCXO (Temperature Compensated Crystal Oscillator 0.5ppM): This highly stable 16.369 MHz oscillator controls the
down conversion process for the RFIC block.
2.4 Physical characteristics
The Jupiter
mount device packaged on a miniature printed circuit board, with a metallic RF enclosure on one side. There are 32 surface
mount connection pads with a base metal of copper and an Electroless Nickel Immersion Gold (ENIG) finish.
