STB5610
GPS RF FRONT-END IC
PRELIMINARY DATA

ONE CHIP SYSTEM TO INTERFACE GPS ANTENNA TO GPS MICRO CONTROLLER ABLE TO SUPPORT ACTIVE AND PASSIVE ANTENNA MINIMUM EXTERNAL COMPONENTS COMPATIBLE WITH GPS L1 SPS SIGNAL AND GALILEO FREQUENCIES CMOS OUTPUT LEVELS 2.7 V .. 3.6 V SUPPLY VOLTAGE EMBEDDED LOW PHASE NOISE PLL ACTIVE ANTENNA SENSOR SMART CHIP ENABLE FUNCTION FOR POWER CONSUMPTION OPTIMIZATION ESD PROTECTED DESCRIPTION The STB5610, using ST Microelectronics RF Bipolar technology, implements a Global Positioning System RF front-end. The chip provides down conversion from the 1575.42 MHz GPS (L1) signal to 4.092 MHz Output signal. The integrated PLL with on-chip reference oscillator uses a low cost 16.368 MHz crystal. No TCXO is required. PIN CONNECTION
