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.
