2 DESCRIPTION
STA2056 is one chip GPS featuring the complete
RF for active antenna systems and baseband
functionality in a QFN 68pin package. STA2056
System-on-Chip combines GPS performances
with low power consumption. Thanks to the few
external components STA2056 makes the appli-
cation simple and smaller.
