DESCRIPTION

The STB5600, using STMicroelectronics HSB2, High Speed Bipolar technology, implements a Global Positioning System RF front-end.

The chip provides down conversion from the GPS (L1) signal at 1575 MHz via an IF of 20MHz to an output frequency of 4MHz suitable for ST20GP1 GPS processor.

It uses a single external reference oscillator to generate both RF local oscillator signals and the processor reference clock.

■ ONE CHIP SYSTEM TO INTERFACE ACTIVE ANTENNA TO ST20GP1 MICROCONTROLLER

■ COMPLETE RECEIVER USING NOVEL DUAL CONVERSION ARCHITECTURE WITH SINGLE IF FILTER

■ MINIMUM EXTERNAL COMPONENTS

■ COMPATIBLE WITH GPS L1 SPS SIGNAL

■ INTERNALLY STABILISED POWER RAILS

■ CMOS OUTPUT LEVELS

■ FROM 3.3 TO 5.9V SUPPLY VOLTAGE

■ TQFP32 PACKAGE
