6V ~ 3.
6V supply Programmable transmit level Programmable pre-emphasis (50/75 µs) Pb-free and RoHS Compliant SOP-16 package Figure 1: KT0803L System Diagram ƒ General Description KT0803L, 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 KT0803K and KT0803M.
The additional features added to KT0803L are standby mode through software, ALC(automatic level control), multiple reference clock, increased SNR performance and frequency response.
The KT0803L 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 KT0803L is configured as an I2C slave and programmed through the industry standard 2-wire MCU interface.
