KT0911 System Diagram
ƒ Description
The KT0911 is a fully integrated AM/FM radio chip with
patented technologies that delivers superior audio and RF
performance, supports direct and simple interface for
tuning wheel and push button, and directly interfaces with
application-specific LCD displays such as SC3610.
Thanks to its advanced system architecture, the KT0911
offers an excellent user listening experience with high
sensitivity, high signal-to-noise ratio, low distortion and
low sensitivity to interference.
KT0911 provides direct and simple interface to support
multiple tuning schemes, such as tuning wheel and push
button. It eliminates many components used in traditional
radios while maintaining the user experience with digital
enhancements.

Information furnished by KT Micro is believed to be accurate and reliable.
However, no responsibility is assumed by KT Micro for its use, nor for any
infringements of patents or other rights of third parties which may result from its
use. No license is granted by implication or otherwise under any patent or patent
rights of KT Micro, Inc.
The unique LO output enables KT0911 to work directly
with the low cost and widely used frequency and clock
display IC, SC3610 and its compatibles, thus offers highly
integrated and low cost AM/FM radio and clock solutions
with digital display.
Thanks to its high integration level, KT0911 lowers the
system cost, simplifies design, and improves product
reliability and manufacturability. KT0911 can operate with
two AAA batteries, making it an ideal for portable radios
that require LCD displays.
