TDA7701 is a single-chip FM Tuner specifically
designed in mixed Bipolar-CMOS technology for
low-voltage/low-power applications, where the
minimization of external component count and
PCB size and complexity are mandatory: typical
examples are mobile phones and portable multi-
media equipment.
Housed in a small TFBGA40 package (5x5 mm), it
features the full FM signal processing chain from
antenna to stereo audio output: RF front-end pro-
cessing, IF processing, demodulation and stereo

C/SPI-controlled tuning with station
detection.
Its low-IF architecture highly integrated RF/IF sec-
tions include a low-noise preamplifier with Auto-
matic Gain Control, an image rejection mixer and
on-chip high-Q channel selection filters that bring
to a minimum the external component count and
PCB complexity while guaranteeing good selectiv-
ity and image-rejection performances Thanks to its
on-chip varactor, the tuning-PLL controlled VCO
needs just one external inductor for low phase-
noise oscillation.
FM demodulation is performed by means of a fully
integrated circuit that eliminates the need for an
external LC tank while maximizing linearity.
The FM stereo signal is decoded through a fullyin-
tegrated, adjustment-free dedicated PLL; auto-
matic signal-dependent stereo blend and soft-
mute functions are provided.
A single external reference frequency is needed
for IC operation, and can be selected among those
commonly used in GSM applications (13/19.2/26/
38.4 MHz + 32768Hz real-time/sleep clock).
