The MT1393ETC FM/RDS Tuner Module is specifically designed to meet the demanding performance targets of automotive customers, at an attractive price. This tuner module has been developed for both FM audio reception as well as RDS/RBDS data reception and includes both an integrated receiving condition analyzer and an integrated RDS/RBDS decoder. The high level of functionality makes this tuner module an ideal solution for use as a dedicated background tuner enabling data services offered via RDS/RBDS and monitoring alternate frequencies. Its excellent sensitivity and strong signal performance produce clear audio and reliable data reception, even under critical receiving situations.
The MT1393ETC is environmentally hardened to operate over an extended temperature range and under adverse climatic conditions and offers a very small form factor for space-critical applications. The tuner section of the module contains a double down-conversion system with a selective pre-filter circuit and image reject mixers. The dynamic selectivity function evaluates the current receiving situation continuously and automatically determines the optimum IF bandwidth. The audio path provides an MPX signal output for external stereo decoding.
The RDS/RBDS portion of the MT1393ETC contains, in addition to the demodulator and decoder, data processing functions including synchronization and error correction. An integrated RAM buffer for up to 24 RBS/RBDS blocks decreases the number of data pulls via the I2C bus. This serial bus is used to control frequency settings and multiple programmable functions of the

The MT1393ETC is a highly integrated FM tuner module with an on-board data decoder for RDS (Europe) as well as RBDS (US).
