TEMIC U6207B-FPG3

U6207B
1.3 GHz PLL with I2C Bus for TV Tuner
Description
The U6207B is a single chip frequency synthesizer with
I2C bus control. This IC contains a high frequency
prescaler which can be switched off. The maximum input
frequency at switched off prescaler is 220 MHz, so that
special channels, e.g. weather forecast channels, can be
received. 3 open collector switching outputs are
available.
Features
D 4 addresses selectable at Pin 7 for multituner
D 1.3 GHz divide-by-8 prescaler integrated
application
(can be bypassed)
D 62.5 kHz (–1.3 GHz)/ 7.8125 kHz (–220 MHz)
D 15 bit counter accepts input frequencies
tuning steps
up to 220 MHz
D Electrostatic protection according to MIL-STD 883
D SO14 package
D mP-controlled by I2C bus

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.
