TEA5762H
NUMBER
The tuning system has an optimized IC partitioning both
from application (omitting interferences) and flexibility
(removable front panel option) point of view: the tuning
synthesizer is on-chip with the radio
The tuning quality is superior and requires no IF-counter
for stop-detection; it is insensitive to ceramic filter
tolerances
In combination with the microcontroller, fast, low-power
operation of preset mode, manual-search, auto-search
and auto-store are possible
The local (internal) controller function facilitates reduced
and simplified microcontroller software
The high integration level means fewer external
components with regard to the communication between
the radio and the microcontroller and a simple and small
Printed-Circuit Board (PCB)
The inherent FUZZY LOGIC behaviour of the Self
Tuned Radio (STR), which mimics hand tuning and
yields a potentially fast yet reliable tuning operation
The level of the incoming signal at which the radio must
lock is software programmable
Two programmable ports
FM-on/off port to control the external FM front-end
High selectivity with distributed IF gain
Soft mute
Signal dependent stereo-blend

PACKAGE
GENERAL DESCRIPTION
The TEA5762 is a 44-pin integrated AM-radio and FM-IF
and demodulator part including a novel tuning concept.
The radio part is based on the TEA5712.
It is designed for the use with an external FM front-end.
The new tuning concept combines the advantages of hand
tuning with electronic facilities and features. User
‘intelligence’ is incorporated into the tuning algorithm and
an improvement of the analog signal processing is used for
the AFC function.
High impedance MOSFET input on AM
Wide supply voltage range of 2.5 to 12 V
Low current consumption 18 mA at AM and FM
(including tuning synthesizer for AM)
Low noise figure
Low output distortion
Due to the new tuning concept, the tuning is
independent of the channel spacing.
