ƒ General Description
KT0806L, our new generation of low cost Monolithic
Digital FM Transmitter, is designed to process high-fidelity
stereo audio signal and transmit modulated FM signal over
a short range. It’s based on the architecture of awardwinning KT0801 and it’s also an upgrade of KT0806. The
additional features added to KT0806L are standby mode
through software, ALC (automatic level control), multiple
reference clock, increased SNR performance and frequency
response.
The KT0806L features dual 20-bit ΔΣ audio ADCs, a highfidelity digital stereo audio processor and a fully integrated
radio frequency (RF) transmitter. An on-chip low-drop-out
regulator (LDO) allows the chip to be integrated in a wide
range of low-voltage battery-operated systems with power
supply ranging from 1.6V to 3.6V.
The KT0806L is configured as an I2
C slave and
programmed through the industry standard 2-wire MCU
interface.
Thanks to its high integration level, the KT0806L is
mounted in a generic 16-pin QFN package. It only requires
a single low-voltage supply. No external tuning is required
that makes design-in effort minimum
