U3665M
Baseband Delay Line 64 s (Improved Version)
Application
In TV sets, the integrated baseband delay line circuit is suitable for decoders with color-difference signal outputs
Description
The integrated delay line circuit U3665M is suitable for A summing circuitry combines the information of
all chroma decoders with baseband color-difference adjacent TV-lines, thus giving an interpolated sum for the
outputs. It is suitable for PAL-, SECAM- and PAL-system, storing preceeding lines for the SECAM-
NTSC-signals as well. The U3665M contains two system and providing a comb-filtered output for
separate delay lines for processing (R–Y)-output and NTSC-signals. Due to internally generated timing,
(B–Y)-output separately. The delay is performed by inter- synchronization is easily done by feeding a line-frequent
nally switched capacitors. On-chip postfiltering avoids impulse (usually the SC-impulse) to the sync-input of
the need for external filter components. In the case of the the IC.
U3665M, the postfilter is tuned to Bessel-characteristic.
Features
One line delay time, addition of delayed and
non-delayed output signals
Line-locked by the sandcastle pulse
No crosstalk between SECAM color
carriers (diaphoty)
Adjustment-free application, VCO without
external components
Comb-filtering functions for NTSC color-
difference signals
Handles negative or positive color-difference
input signals

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.
