U4283BM
AM / FM - PLL
Description
2
The U4283BM is an integrated circuit in BICMOS by I C bus. The device is designed for all frequency
technology for frequency synthesizer. It performs all the synthesizer applications of radio receivers, as well as
functions of a PLL radio tuning system and is controlled RDS (Radio Data System) applications.
Features
Reference oscillator up to 15 MHz
Three programmable switching outputs
(open drain up to 20 V)
Two programmable 16 bit dividers
adjustable from 2 to 65535
Few external component requirements due
to integrated loop-transistor for AM/FM
Fine tuning steps: AM 1 kHz
FM 2 kHz
High signal/ noise ratio

Functional Description
The U4283BM is controlled via the 2-wire I C bus. For Each transmission on the I C bus begins with the
programming there are one module address byte, two “START”-condition and has to be ended by the “STOP”-
2
2
subaddress bytes and five data bytes.
condition (see figure 3).
The module address contains a programmable address bit
A 1 which with address select input AS (Pin 4) makes it
possible to operate two U4283BM-B in one system. If bit
A 1 is identical with the status of the address select input
AS, the chip is selected.
The integrated circuit U 4283 BM has two separate inputs
for AM and FM oscillator. Pre-amplified AM signal is
directed to the 16 bit N-divider via AM/FM switch,
whereas (pre-amplified) FM signal is first divided by a
fixed prescaler (:2). AM/FM switch is controlled by
software. Tuning steps can be selected by 16 bit
R-divider. Further there is a digital memory phase
detector. There are two separate current sources for AM
and FM amplifier (charge pump) as given in electrical
characteristics. It allows independent adjustment of gain,
whereby providing high current for high speed tuning and
low current for stable tuning.
The subaddress determines which one of the data bytes is
transmitted first. If subaddress of R-divider is
transmitted, the sequence of the next data bytes is DB 0
(Status), DB 1 and DB 2.
If subaddress of N-divider is transmitted, the sequence of
the next data bytes is DB 3 and DB 4. The bit organisation
of the module address, subaddress and 5 data bytes are
shown in figure 2

Ozone Depleting Substances Policy Statement
It is the policy of TEMIC TELEFUNKEN microelectronic GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems
with respect to their impact on the health and safety of our employees and the public, as well as their impact on
the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as
ozone depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and
forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban
on these substances.
TEMIC TELEFUNKEN microelectronic GmbH semiconductor division has been able to use its policy of
continuous improvements to eliminate the use of ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively
2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency (EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.
TEMIC can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain
such substances.
We reserve the right to make changes to improve technical design and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each customer
application by the customer. Should the buyer use TEMIC products for any unintended or unauthorized
application, the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of,
directly or indirectly, any claim of personal damage, injury or death associated with such unintended or
unauthorized use.
