Description
The TDA7528 is a frontend module for use in car
radio receivers on the 50kHz - 108MHz and
161MHz - 163 MHz frequency bands. Its field of
use includes all the current radio broadcast
services worldwide for AM radio (long, medium
and short wave), FM radio (US, European,
Japanese and OIRT bands) and US weather
band. Digital standards such as DRM and HD
radio (IBOC) can also be handled.
The system is designed to be single super-
heterodyne with an intermediate frequency of
10.7 MHz. The IF signal is digitized, filtered and
demodulated in the appropriate STA3005
backend IC.
The combination of two independently-operating
frontends with the STA3005 backend makes DDA
(Digital Directional Antenna) operation possible or
the simultaneous reception of two freely-
selectable frequencies with any combination of
types of demodulation.
The TDA7528 frontend IMR mixer has separate
input and output stages for AM frequency bands
up to 30MHz (narrowband services) and for FM
frequencies above 30MHz (broadband signals).
As an option, the AM path can be operated with
an integrated preamplifier stage and an integrated
low-pass filter to reduce interfering input signals
on the IF and image frequencies. The FM mixer
has two inputs: the more sensitive (lower noise)
input is intended for use with a low-gain, passive
pre-selection stage; the second input is intended
for use with an active preamplifier stage yielding a
high level signal calling for a higher IP3.
