ƒ Description
The KT0830EG is a high-quality Monolithic Digital FM
Receiver designed to playback high-fidelity FM broadcasting
signals under various conditions.
The KT0830EG 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 2.0V to 3.6V consuming merely
19mA in full operation mode and less than 10uA when standby
– greatly extending the battery life.
The small footprint, high integration level and great flexibility
make KT0830EG for any standalone FM radio applications.

The register bank stores channel frequency codes, calibration parameters, operation status,
mode and power controls, which can be accessed by the internal digital controller, state
machines and external micro controllers through the serial interface.
All registers are 16 bits wide. Control logics are active high unless specifically noted. All
the registers are automatically set to default values after the chip is powered-on or
reset.
