Monolithic Digital Stereo FM Transmitter Radio-Station-on-a-Chip™ KT0803L
Features Hardware compatible with KT0803K and KT0803M Additional features to KT0803K and KT0803M Software standby; Automatic power down power amplifier when silence is detected; Multiple reference clock support including from 32.768KHz to 26MHz; ALC (Automatic Level Control) Higher SNR (Stereo: 66dB) Increased audio frequency response Software controlled XTAL selection Professional Grade Performance: SNR ≥ 66 dB Stereo Separation > 40 dB Figure 1: KT0803L System Diagram International compatible 70MHz ~ 108MHz Ultra-Low Power Consumption: < 17 mA operation current
General Description < 3 µA standby current
KT0803L, our new generation of low cost Monolithic
Simple Interface:
Digital FM Transmitter, is designed to process high-fidelity
Single power supply
stereo audio signal and transmit modulated FM signal over
Standard 2-wire I2C MCU interface
a short range. It’s based on the architecture of award-
Advanced Digital Audio Signal Processing:
winning KT0801 and it’s also an upgrade of KT0803K and
On-chip 20-bit ΔΣ Audio ADC
KT0803M. The additional features added to KT0803L are
On-chip DSP core
standby mode through software, ALC(automatic level
On-chip 24dB PGA with optional 1dB step
control), multiple reference clock, increased SNR
Automatic calibration against process
performance and frequency response.
and temperature 1.6V ~ 3.6V supply
The KT0803L features dual 20-bit ΔΣ audio ADCs, a high-
Programmable transmit level
fidelity digital stereo audio processor and a fully integrated
Programmable pre-emphasis (50/75 µs)
radio frequency (RF) transmitter. An on-chip low-drop-out
Pb-free and RoHS Compliant
regulator (LDO) allows the chip to be integrated in a wide
SOP-16 package
range of low-voltage battery-operated systems with power supply ranging from 1.6V to 3.6V.
Applications MP3 Player, Cellular Phone, PDA, PND,
The KT0803L is configured as an I2C slave and
Portable Personal Media player and its accessory,
programmed through the industry standard 2-wire MCU
Laptop Computer, Wireless Speaker
interface.
Rev. 1.3
Thanks to its high integration level, the KT0803L is mounted in a generic 16-pin SOP package. It only requires Information furnished by KT Micro is believed to be accurate a single low-voltage supply. No external tuning is required and reliable.
