`
The NXP TEF7006 and TEF7007 deliver automotivequalified performance while enabling compact, low-cost
implementation of FM-RDS background receivers. `
They perform all the radio and audio functions, building on
NXP’s market-leading technologies for low-IF tuners and `
digital low-IF car DSPs, and digitally processed RDS
demodulation and decoding based on NXP’s proven
technology. The TEF7007 adds an integrated FM antenna
buffer, to simplify the development of systems that require
buffering. Both devices are completely adjustment-free and
require only a small number of external components. The very
high level of integration makes it easy to obtain a very compact
design.
The FM receivers in both devices cover the Japan/EU/USA
bands from 76 to 108 MHz and are able to decode data from
Radio Data System (RDS), Radio Broadcast Data System (RBDS),
and Traffic Message Channel (TMC) services. DARC/VICS
decoders are supported as well, via the MPX output.
Excellent tuner characteristics, along with the ability to detect
all relevant weak signal conditions, make it possible to use
these devices as equivalent receivers for background station
list generation and updates.
The devices can be used in combination with NXP’s digital
low-IF car DSP systems (TEF7000 & SAF774x) for car radio/
audio applications. They can interface to the car DSP clock
reference, or can use a crystal oscillator operating at `
16 MHz. The reception quality and performance are similar
to that of the main tuner, and therefore optimized for
background receiver functions. Both devices can also operate
as standalone TMC receivers in navigation units or in Traffic
Information Message (TIM) recording applications.
output, and also at digital I²S-bus audio interface. That way,
both interfaces can support either TIM recording devices that
use analog or digital inputs.
Both devices use an on-chip, highly linear and AGC-controlled
FM LNA and mixer for best image rejection. In combination
with a fast PLL tuning system, which controls a fully integrated
low-phase-noise VCO, the desired FM signal is converted
to a complex 250 kHz IF. To optimize reception quality, the
low- or high-side injection mode of the local oscillator (LO)
is automatically selected. Each device also uses integrated
IF filtering, with a four-step switchable IF filter bandwidth
function, to achieve optimal FM demodulation. The I2C bus
provides and reads the following detectors: field strength/
RSSI (LEVEL), multipath (WAM - Wideband AM), noise (USN UltraSonic Noise), and IF counter information (IFCOUNT).
Superior RDS sensitivity is achieved by optimized digital
filtering and signal processing. The RDS decoder includes
a memory for two data blocks, and provides fast block
synchronization and error detection. The RDS data blocks
and status info can be read via the I²C-bus. Hardware pins are
provided for the RDS data-available interrupt flag (DAV_N), and
the RDS clock and demodulator data stream outputs RDCL and
RDDA. These pins can alternatively be used as software ports.
The TEF7006 and TEF7007 generate a MultiPleX (MPX) output
signal, followed by a digitally realized RDS demodulation and
decoding block. The MPX output also supports Data Radio
Channel (DARC) formats, including Vehicle Information and
Communication System (VICS) decoders. A mono audio signal
with an integrated bandwidth filter is available at an analog
All functions are controlled using the Fast-mode I²C-bus up to
400 kHz. The I²C-bus also provides access to all weak signal
detectors and other status information.
The two devices are pin-compatible and available in a thin
HVQFN plastic quad flat package with 32 terminals (no
leads, pitch 0.5 mm) and a body size of 5 x 5 x 0.85 mm. The
complete application can be supported by a small, low-cost,
dual-layer PCB.
