KT0932

产品概述
The KT0932 is KT Micro’s latest generation of proprietary fully integrated AM/FM receiver chip supporting mechanical tuning without MCU. The new features include improved tuning feel, new ST and Tuning light signal, improved EMI/EMC, improved FM stereo separation and improved flatness of sensitivity.
 
Thanks to its advanced architecture, KT0932 offers an excellent user listening experience with high sensitivity, high signal-to-noise ratio, low distortion and low sensitivity to interference.
 
KT0932 provides direct and simple interface to support mechanical tuning. A pre-programmed low cost EEPROM can be used to configure the radio settings to differentiate product designs and accommodate standards in various regions. No external MCU is required.
 
Thanks to its high integration level and efficient user interface design, KT0932 lowers the system cost, simplifies design and improves product reliability and manufacturability. KT0932 can operate with two AAA batteries, making it ideal for low-power portable radio.
