Product Brief QN8006/8006L
High Performance Digital FM Transceiver for Portable Devices
________ General Description ________
__________ Key Features __________
• Worldwide FM Band Receive and Transmit
• 76 MHz to 108 MHz full band tuning in
50/100/200 kHz step sizes
The QN8006 is a high performance, low power, full-
featured single-chip stereo FM transceiver designed for cell
phones, GPS personal navigation devices, portable
audio/video players, and automotive accessories. The
QN8006 covers frequencies from 76 MHz to 108 MHz in
50/100/200 kHz step sizes for worldwide FM band support.
The QN8006 also supports RDS/RBDS data transmit and
receive.
• 50/75μs pre-emphasis and de-emphasis
• Ease of Integration
• Small footprint, 4 x 4 x 0.85mm QFN24
• Only 2 external passive components required
• Adaptive antenna tuning
• Low cellular and GPS band spurs
• High Immunity to TDMA (GSM/GPRS) burst noise
• Multiple crystal frequencies supported
• 2- and 3-wire control interfaces
The QN8006 integrates both FM receiving and transmitting
functions, including RF front-end circuits (PA, LNA, and
channel selective filter), full digital FM modulator/
demodulator, MPX codec, pre-emphasis/de-emphasis and
feature-rich audio processing (audio AGC, soft clipping,
SM, HCC, and SNC). Auto Seek and clear channel scan
functions enable automatic channel selection for best sound
quality. Integrated antenna tuning eases antenna matching
in real applications. The QN8006 provides both digital and
analog audio interfaces. 2-wire and 3-wire digital control
interfaces provide simple access to programmable functions.
• Very Low Power Consumption
• 11.5mA (Transmit Mode), 18.8mA (Receive Mode)
• Integrated voltage regulator, direct connect to battery
• Power saving idle and standby modes
• Low shutdown leakage current
• High Performance FM Receiver (FMR)
• Superior sensitivity 1.4µVEMF
• 66dB Stereo SNR, 0.03% THD
• High interference rejection
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. The QN8006 is ideal for cellular
handsets and GPS personal navigation applications.
• Integrated audio processing (SNC, HCC, SM)
• Auto Seek
• High Performance FM Transmitter (FMT)
• 66dB Stereo SNR, 0.03% THD
• Maximum 124dBuV RF output level with 42dB
adjustable range
The QN8006’s small footprint, high integration with
minimum external component count, and support for
multiple clock frequencies make it easy to integrate into a
variety of small form-factor low-power portable
applications. Integrated low-phase noise digital synthesizers
and extensive on-chip auto calibration ensures robust
consistent performance over temperature and process
variations. An integrated voltage regulator enables direct
connection to a battery and provides high PSRR for superior
noise suppression. A low-power idle mode extends battery
life.
• Integrated Clear Channel Scan
• RDS/RBDS Transmit & Receive
• Supports US and European data service,
including TMC (Traffic Messaging Channel)
(not available in QN8006L)
• Flexible Audio Interfaces
• Digital audio interface supports I2S and a variety of
PCM data formats with 4 different data rates
• Programmable analog audio input/output
• Integrated audio AGC and soft clipping
ESD protection is on all pins. The QN8006 is fabricated in
highly reliable CMOS technology.
• Robust Operation
• -250C to +850C operation
• ESD protection on all input and output pads
