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.
