The KT0935R is KT Micro’s 3rd generation of proprietary fully integrated FM/MW/SW receiver chip that upgrades the performance, improves the user experience and eases integration and manufacturing efforts. The new features include improved flatness of sensitivity on the whole band, independent status indicator, improved EMI/EMC and higher FM stereo separation.
Thanks to the patented tuning technology, the receiver maintains good signal reception even with short antennas. The chip consumes merely 29mA current and can be powered by 2 AAA batteries. Another useful feature is that the volume and channel information can be preserved in standby mode without external memories. KT0935R integrated RDS/RBDS decoder that can receive RDS/RBDS broadcasted both in American and European area. KT0935R supports a wide range of reference clocks from 30 KHz to 40 MHz, hence can share system clocks with a varieties of MCUs further reducing the system BOM cost. The KT0935R has different user interface schemes like other parts in the KT093x family.
With high audio performance, fully integrated features and low BOM cost, KT0935R is ideal for various applications and products that require flexible programmability for rich features.
