The KT0922-D4 is KT Micro’s 2nd 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 one audio line-in channel.
Thanks to its advanced architecture, KT0922-D4 offers an excellent user listening experience with high sensitivity, high signal-to-noise ratio, low distortion and low sensitivity to interference.
KT0922-D4 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, KT0922-D4 lowers the system cost, simplifies design and improves product reliability and manufacturability. KT0922-D4 can operate with two AAA batteries, making it ideal for low-power portable radio.
