QN8075
Single-Chip Low-Power FM Receiver for Portable Devices
__________________________ General Description __________________________
The QN8075 is a high performance, low power; full-featured single-chip stereo FM receiver designed for mini-speakers,
MP3 players. It integrates FM receive functions, auto-seek and clear channel scan. Advanced digital architecture enables
superior receiver sensitivity and crystal clear audio.
With its small footprint, minimal external component count and multiple crystal clock frequency support, the QN8075 is
easy to integrate into a variety of small form-factor low power portable applications.
