GENERAL DESCRIPTION
The AS6001/AS6002 is an
innovative highly integrated FM stereo
transmitter. It is the first generation of
FM transmitter IC designed using
Accel’s patent-pending RF technology.
It consists of a stereo encoder and
FM transmitter. 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.
The AS6001/AS6002 is designed
for portable application as well as
general application. The 1.8V operation
voltage and as low as 18mA quiescent
current make it extremely suitable for
portable devices such as MP3 and
mobile phone. It also embeds LDO
power regulator to make power supply
design easy and flexible.
The AS6001 has a 3-wire digital
control interface for external controller
easy and flexible to program and control
the transmitting channel. The
transmitting channel is from 87 to 108
MHz with 0.1MHz step continuous
tuning. So it is suitable for China,
Europe and North America.
