Description
The KT0913L-D4 is KT Micro’s latest generation of proprietary fully integrated AM/FM receiver chip that upgrades the performance, improve the user experience and ease integration and manufacturing efforts. The new features includes the additional audio input, independent status indicator, improved EMI/EMC.
Thanks to the patented tuning technology, the receiver maintains good signal reception even with short antennas. The chip consumes merely 25mA 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. KT0913L-D4 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. KT0913L-D4
With high audio performance, fully integrated features and low BOM cost, KT0913L-D4 is ideal for various applications and products that require flexible programmability for rich features.
