QN8006B/8006LB
High Performance Digital FM Transceiver for Portable Devices
__________________________ General Description __________________________
The QN8006 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, unsurpassed spectral purity, ultra-low harmonic and spurious levels, and high immunity to
TDMA burst noise.
With its small footprint, minimal external component count and multiple clock frequency support, the QN8006 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 QN8006 is fabricated in highly reliable CMOS technology.
