ƒ General Description
KT0801A, 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 award-
winning KT0801 and it’s also an upgrade of KT0801. The
additional features added to KT0801A are increased
transmission power up to 113 dBuV, support of 32.768
KHz input clock and crystal, bass control and auto level
detection.
The KT0801A features dual 20-bit ΔΣ audio ADCs, a high-
fidelity 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 KT0801A is configured as an I2C slave and
programmed through the industry standard 2-wire MCU
interface.
.
Thanks to its high integration level, the KT0801A is
mounted in a generic 24-pin QFN package. It only requires
a single low-voltage supply. No external tuning is required
that makes design-in effort minimum.
