QN8036
High Performance Digital FM Transceiver for Portable Devices
__________________________ General Description __________________________
The QN8036 is a high performance, low power, fully integrated single-chip stereo FM transceiver designed for cell phones, PMP/PNDs, and portable radios. It integrates both FM receiving and transmitting functions, auto-seek and clear channel scan, and antenna tuning to ease matching in real applications. Advanced digital architecture enables superior receiver sensitivity, crystal clear audio.
With its small footprint, minimal external component count and multiple clock frequency support, the QN8036 is easy to integrate into a variety of small form-factor low power portable applications. An integrated voltage regulator enables direct connection to a battery and provides high PSRR for superior noise suppression. A low-power Standby mode extends battery life. ESD protection is on all pins. The QN8036 is fabricated in highly reliable CMOS technology.
