FEATURES
Highly integrated FM stereo transmitter Patent-pending architecture Low power operation, extremely suitable for portable devices Ultra low standby current in 10uA with PDN enable LDO embedded for easy power supply design 3-wire digital control interface for flexible channel programming and control (AS6001) 4-wire parallel control interface for easy channel programming and control (AS6002) 87 – 108 MHz with 0.1MHz step PLL-based continuous tuning for China, Europe and North America (AS6001) 87.7 – 88.9MHz and 106.7 – 107.9MHz with 0.2MHz step PLL-based continuous tuning (AS6002) Less off chip components Small footprint SSOP-20 and QFN-20 package GENERAL DESCRIPTION
The stereo encoder is based on signal processing to encode analog stereo audio input signal and generate a composite FM signal with MAIN, SUB and pilot signal from a 7.6MHz oscillator. The FM transmitter uses direct frequency synthesis to radiate FM wave to the air by modulating the carrier signal with the composite signal.
