Productinfo
The TUA 4401K is the first Infineon
Carradio IC using BICMOS technol-
ogy.
The combination of an analog FM
receiver circuit and a digital PLL syn-
thesizer on the same chip reduces the
over all pin count in comparison to two
separate IC’s and in addition the
number of necessary external compo-
nents. This gives the flexibility both for
high performance and low cost appli-
cations.
The recommended applications for this
device are FM only carradios and back-
ground receivers, capable for all world
standards.
