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.
