NXP FM-RDS/TMC

background receivers

TEF7006 & TEF7007

High-performance FM car radio

receivers for background scanning

These`advanced`devices,`which`are`able`to`decode`data`from`RDS,`RBDS,`and`TMC`services,`can`

also`be`used`as`equivalent`receivers`for`background`station`list`updates.

Key features

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.

``Compact,`highly`integrated,`and`pin-compatible`devices

``Lowest`total`system`cost`when`combined`with`other`NXP`

offerings

-`Low-IF`DSP`family`SAF774x

-`High-efﬁciency,`one-chip`radio`family`TEF663x

``Support`standalone`operating`mode`with`quartz`crystal

``Fast-mode`I²C`bus`(400`kHz)

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.

``Single`5`V`supply`voltage

``AEC-Q100`qualiﬁed

``HVQFN32`package`(5`x`5`x`0.85`mm,`0.5`mm`pitch)

The`NXP`TEF7006`and`TEF7007`deliver`automotive-

qualiﬁed`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`

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` Superior`RDS`sensitivity`is`achieved`by`optimized`digital`

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).`

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.

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`TEF7006`and`TEF7007`generate`a`MultiPleX`(MPX)`output` The`two`devices`are`pin-compatible`and`available`in`a`thin`

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`

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,`

Communication`System`(VICS)`decoders.`A`mono`audio`signal` dual-layer`PCB.`
