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
