These tuner modules are designed for different standards in the US, Europe, and Japan, giving them “world” tuner functionality. The AM section contains an up/down conversion system with an active prestage and an audio output. Software can control the basic parameters such as AGC threshold. Features such as the highly sophisticated filter technology at both intermediate frequencies and the complex AGC functionality help ensure that the 1383 series tuners provide high-end AM performance. The FM section contains a double down-conversion system with an active prestage and an MPX signal output. Using appropriate external signal processing, the stereo signal and the RDS/RBDS data can be derived from the MPX signal. The receiving condition analyzer for output field strength, adjacent channel, multipath, and deviation, allows continuous evaluation of the received signal. This feature, together with the ability to change parameters such as IF bandwidth (50 kHz to 200 kHz), IF amplifier gain, or AGC threshold via an external microprocessor, provides ease of system integration and helps ensure optimum performance in almost every situation. These capabilities, coupled with the integrated multipath noise blanker, produce clear sound with minimal noise and interference even in the most critical receiving situations. The very short response time of the PLL and of the outputs of the receiving condition analyzer support RDS applications in such a way that evaluations of alternative frequencies can proceed very quickly with no audible interference. A three-wire bus controls band selection, tuning, and the multiple tuner functions.
