6V supply Programmable transmit level Programmable pre-emphasis (50/75 µs) Pb-free and RoHS Compliant Figure 1: KT0801A System Diagram 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 awardwinning 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 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 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 requ...
