FEATURES Local/DX switching to improve large signal handling on FM when an outdoor antenna or cable network is connected MPX-RDS signal available The module meets the "FCC regulations" Small size. GENERAL DESCRIPTION The is a global FM-radio tuner (except Japan) which includes a brand new concept in tuning techniques. The new tuning concept combines the advantages of hand tuning together with electronic facilities and features. TOP VIEW ORDERING INFORMATION UNIT OM5610 FREQUENCY (MHz) to 108

In preset mode, the microcontroller has to load information such as frequency band, frequency and mono/stereo. This information has to be sent via the bus to the tuner. The internal algorithm controls the tuning sequence as follows: 1. The information is loaded into a shift register, a last-station memory and the counter. 2. The Automatic Frequency Control (AFC) is switched-off. 3. The counter starts counting the frequency and the tuning voltage is varied until the real frequency roughly equals the desired frequency. 4. The AFC is then switched on and the real frequency is more precisely tuned to the actual IF frequency. 5. After the AFC has tuned the real frequency to the desired frequency an in-lock signal is generated; then the counter is switched off. In order to get a reliable in-lock signal, there are two parameters measured: the field strength and the S-curve. 6. The field strength indicates the strength of the station and by looking at the S-curve the system can detect an in-lock situation. In the event of fading or pulling the in-lock signal becomes logic 0 and the synthesizer will be switched on again (maintaining last station) and the algorithm will be repeated. SEARCH OPERATION During a search operation, the only action the microcontroller has to take is: sending the desired band plus the direction and the search sensitivity level to the tuner. The search operation is performed by the charge pump until an in-lock signal is generated (combination of measuring the field strength and the S-curve). By looking at the S-curve the system can distinguish false in-locks from real in-locks (false in-locks occur on the wrong slope of the S-curve). The AFC then fine tunes to the station. The frequency of the found station will be counted by the counter and written into the last-station memory and the shift register of the counter. At this time the frequency is available in the shift register and can be read by the microcontroller. The microcontroller decides whether the frequency is within the desired frequency band. If so, this frequency can be stored under a preset and if not, a new search action should be started.
FUNCTIONAL DESCRIPTION The is an integrated FM stereo radio circuit including digital tuning and control functions. The radio The radio circuit incorporates a tuned RF stage, a double balanced mixer, a one-pin oscillator and is designed for distributed IF ceramic filters. The FM quadrature detector uses a ceramic resonator. The PLL stereo decoder incorporates a signal dependent stereo-blend circuit and a soft-mute circuit. Tuning The tuning-concept of Self Tuned Radio (STR) is based on FUZZY LOGIC: it mimics hand tuning (hand tuning is a combination of coarse and fine tuning to the qualitatively best frequency position). As a consequence the tuning system is very fast. The tuning algorithm, which is controlled by a sequential circuit, is completely integrated; so there are only a few external components needed. The bus and the microcontroller can be kept very simple. The bus only consists of three wires (CLCK, DATA and WREN). The microcontroller must basically give two instructions: Preset operation Search operation.
