GS1299
General Description
The GS1299 is a single-chip broadcast FM stereo
radio tuner with fully integrated synthesizer, IF
lectivity and MPX decoder. The tuner us the
CMOS process, require the least external
component. The package size is SOP16 and is
completely adjustment-free. All the make it very
suitable for portable devices.
The GS1299 has a powerful low-IF digital audio
processor, this make it have optimum sound quality
with varying reception conditions.
The GS1299 can be tuned to the worldwide
frequency band.
