| U2861B Mono FM Sound Demodulator for TV Systems Description The U2861B is an alignment-free FM sound IF demodulator for all TV standards from 4.5 MHz up to 6.5 MHz (standard M, N, B/G, I, D/K). The circuit includes two switchable audio inputs and volume control. With a supply voltage of 5 V, the U2861B is suitable for TV, VCR and Multimedia applications.

A2, 23-Feb-01 1 (11) Extended Type Number U2861B - M U2861B - MFPG3 Package DIP14 SO14 Remarks U2861B Circuit Description Sound IF Limiter Amplifier The intercarrier signal coming from the sound filter is fed to a 7-stage limiter amplifier. This guarantees high input sensitivity and excellent AM suppression. Audio Switch 1 The first audio switch (Pin 13) has inputs for the demodulated FM signal and the external AF1 signal from Pin 1. For multistandard purposes, it is possible to handle internal FM and external AM audio signals. The output of switch1 is also permanently available at Pin 12 (e. g. for SCART interface). PLL - FM Demodulator The alignment-free "Phase-Locked-Loop" (PLL) FM demodulator covers a wide frequency range of 4.5 MHz up to 6.5 MHz with excellent noise performance. Due to the fact that the voltage-to-frequency characteristic is linear, a low harmonic distortion can be achieved. The free-running frequency of the internal VCO circuit is about 5.5 MHz. The demodulated FM signal is led via de-emphasis and buffered to Pin 12. The de-emphasis low pass filter consists of an internal 5-kW series resistor and an external capacitor at Pin 14. The FM muting is possible by switching Pin 5 to ground. Audio Switch 2 and Volume Control The second audio switch (Pin 11) has inputs for the audio signal from switch 1 and the external AF2 signal at Pin 10. The switched AF signal is fed to volume control. The output voltage can be controlled by a DC voltage at Pin 9. Internal Voltage Stabilizer The internal bandgap reference ensures constant performance independent of supply voltage and temperature.

A2, 23-Feb-01 U2861B Ozone Depleting Substances Policy Statement It is the policy of Atmel Germany 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. Atmel Germany GmbH 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. Atmel Germany GmbH 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 Atmel Wireless & Microcontrollers products for any unintended or unauthorized application, the buyer shall indemnify Atmel Wireless & Microcontrollers 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.
