NXP low-IF analog car radio
tuners TEF662x
Easy-to-use, cost-effective tuners
for analog car radios
Building`on`the`success`of`NXP’s`TEF660x`and`TEF661x`families,`the`TEF662x`uses`a`low-IF`
architecture`to`ensure`high`integration`with`low`complexity.`The`result`is`easy`design-in`and`
best-in-class`price/performance`ratios.
Key features
Key applications
``Highly`integrated`tuners`with`low-IF`conversion
``PLL`synthesizer`with`integrated`VCO
``Integrated`AM`LNA`with`AGC`and`RF`selectivity`
(TEF6623`is`FM-only)
``Aftermarket`car`radios
``Consumer`radio
These`tuners`integrate`all`the`critical`RF`components,`so`
they’re`easy`to`design`onto`the`main`radio`board.`There’s`no`
need`for`a`tuner`module,`and`no`alignments`are`required.`
``Integrated`FM`LNA`with`AGC
``Stereo`decoder`with`output`for`interfacing`with`external`
analog`or`digital`audio`processor
``Advanced`weak`signal`processing`(soft`mute,`stereo`blend,`
high`cut`control)
The`performance,`feature`set,`and`quality`of`the`TEF662x`
family`are`optimized`to`enable`complementary`pricing`and`
product`positioning`for`the`cost-sensitive`aftermarket`car`
radio`and`consumer`segments.`All`the`devices`in`the`family`
are`software-`and`hardware-`(pin-to-pin`and`application)`
compatible`with`each`other`as`well`with`devices`from`the`
TEF660x`and`TEF661x`families.`This`allows`a`single`reference`
tuner`design`to`address`a`range`of`requirements.
``PACS
``FM`noise`blanker
``Signal`quality`detection
``I2C-bus`control
``RDS`demodulator`(TEF6623`&`24`only)
``Single`8.5`V`supply
``SO32`package
``Very`low`external`component`count
``Allows`for`fast`software`development`because`of`
integrated`radio`knowledge`and`easy`interface
``Very`good`strong`signal`behavior`
Low-IF architecture
Many`existing`solutions`require`double`IF`(intermediate`
frequency)`conversion.`NXP’s`low-IF`architecture`eliminates`
the`10.7`MHz`and`450`kHz`IF`transformer`coils`and`ceramics,`
as`well`as`the`expensive`external`components`needed`for`LNA` or`resources`can`design`the`TEF662x`onto`the`main`PCB`
and`AGC`in`the`AM`and`FM`front-ends.`The`TEF662x`family`
also`integrates`a`VCO,`so`there’s`no`need`for`external`LC`tank`
components.`
board,`saving`significant`costs`by`making`a`tuner`module`
design`obsolete.`Manufacturing`is`also`easier,`since`full`SMD`
applications,`without`hand`mounting,`are`possible.`Production`
throughput`can`be`higher,`too,`because`there`are`fewer`small`
external`components`to`handle,`and`there`are`no`mechanical`
or`software`alignments`to`be`made.
The`low-IF`architecture`simplifies`PCB`layout,`since`there`
aren’t`any`critical`high-frequency`lines`and`there’s`no`need`
for`alignments.`Even`designers`with`limited`RF`know-how`
