The GS1288 is a high-quality Monolithic Digital FM Receiver
designed to playback high-fidelity FM broadcasting signals
under various conditions.
The GS1288 offers a true single-chip FM radio solution with
no need of MCU to control the operation. There are no external
filters or frequency-tuning devices thanks to a proprietary
digital low-IF architecture, a fully-integrated LNA, automatic
gain control (AGC), high-performance ADCs, high-quality
analog and digital filters, and an on-chip low-noise self-tuning
VCO. The on-chip high-fidelity Class-AB driver further
eliminates the need for any external audio amplifiers and can
drive stereo headphones directly.
The on-chip LDO regulator allows the chip to operate with
power supply ranging from 1.8 V to 3.6V consuming merely
18mA in full operation mode and less than 1uA when standby
– greatly extending the battery life. The programmable Bass
Boosting effect ensures an uncompromised listening
experience and suit a wide range of tastes.
The small footprint, high integration level and great flexibility
make GS1288 for any standalone FM radio applications.
