ƒ Description
The KT0830E is a high-quality Monolithic Digital FM
Receiver designed to playback high-fidelity FM broadcasting
signals under various conditions.
The KT0830E offers a true single-chip FM radio solution.
There are no external filters or frequency-tuning devices
thanks to a proprietary digital low-IF architecture, a fully-
integrated LNA, automatic gain control (AGC), high-
performance ADCs, high-quality analog and digital filters, and
an on-chip low-noise self-tuning VCO. The on-chip high-
fidelity Class-AB driver further eliminates the need for any
external audio amplifiers and can drive stereo headphones
directly.
The on-chip LDO regulator allows the chip to operate with
power supply ranging from 1.8 V to 3.6V consuming merely
19mA in full operation mode and less than 20uA when standby
– greatly extending the battery life.
The small footprint, high integration level and great flexibility
make KT0830E for any standalone FM radio applications.

KT0830E
3.3.2 Mute
KT0830E can be hard muted by setting MUTE_B to 0 and the output of the audio
signal is set to the common mode voltage.
There is also a Soft Mute feature that is enabled by setting SMUTE_B to 0. In this
mode, the audio volume is gradually attenuated when the signal reception is bad (i.e.
when the RSSI is below a certain level as defined by SMTH<1:0>.) The attenuation
attack rate and depth can be configured through SMUTER<1:0> and
SMUTEA<1:0>, respectively.
3.3.3 Stereo / Mono Blending
In order to provide a comfortable listening experience, KT0830E blends the stereo
signal with mono signal gradually when in weak reception. The signal level range
over which the blending occurs is set by BLNDADJ<1:0>. The blending is disabled
when DBLND is set to 1. MONO playback mode can also be forced by setting the
MONO to 1.
3.3.4 Bass Boosting
KT0830E provides a digital audio enhancement feature, bass boosting. The gain of
the bass boost can be programmed through BASS<1:0> (Reg0x04<9:8>). With
BASS<1:0>=00, this feature is disabled.
3.4 Stereo DAC, Audio Filter and Driver
Two high-quality single-bit ΔΣ audio digital to analog converters (DAC) are
integrated along with high-fidelity analog audio filters and class AB drivers.
Headphones and speakers with impedance as low as 16ohms can be directly driven
without external audio drivers. An integrated anti-pop circuit eliminates the click-
and-pop sound during power up and power down.
3.5 SEEK/TUNE
The fully integrated LO synthesizer supports wide band operation from 64MHz to
110MHz. The reference clock is 32.768 kHz with frequency tolerance of ±100ppm.
The chip begins to directly TUNE to a channel when the register TUNE is set to 1.
The channel frequency can be programmed and tuned by setting CHAN<9:0> and
can be defined as
Freq(MHz) = 50 kHz × CHAN<9:0> + 64 MHz
The SEEK process is started by setting SEEK to “1”. The seek direction is
determined by SEEKUP. The band edges are determined by BAND<1:0> and the
seek step is set by SPACE<1:0>. KT0830E automatically seeks and tunes to the first
satisfying station. The seeking criterion is set by SEEKTH<3:0>. If no qualified
channel is found, the FM receiver returns to the original channel and SF/BL bit is set
to “1”. When AUTOTUNE bit is set to 1, the chip will automatically tune to the
found channel, otherwise, the chip will remain mute after seek is completed. During
the seeking, the current channel can be read out from READCH<9:0> bits.
