1. Description  
The ATR0603 is a single-IF GPS front-end IC, designed to meet the requirements of  
mobile and automotive applications. Excellent RF performance combined with high  
bandwidth and a low noise figure enables high-quality GPS solutions, and its very low  
power consumption is a perfect match for portable devices. Featuring a fully inte-  
grated balanced frequency synthesizer, only a few external components are required.  
The gain of the IF amplifier can be set to three different levels in order to meet the  
requirements for various applications. Several types of external oscillators can be con-  
nected to the robust TCXO interface. The startup logic allows significant power saving  
due to very low power-down current and the ability to disable the external TCXO or  
even other external components. CMOS output drivers deliver a 1-bit data signal and  
a 16.367667-MHz clock signal to the baseband interface.
