The KT0913 is a fully integrated digital AM/FM radio receiver chip that offer full band AM/FM functionality, high quality audio performance, simple design and low BOM cost thanks to the minimum external components required and direct frequency and volume control interface without requiring customers to modify existing exterior module.
The receiver maintains good signal reception even with short antennas. The chip consumes merely 22mA 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. KT0913 supports a wide range of reference clocks from 32.768KHz to 26MHz, hence can share system clocks with a varieties of MCUs further reducing the system BOM cost.
With high audio performance, fully integrated features and low BOM cost, KT0913 is ideal for various applications and products.
