MT1467 Tuner Module
杨贵妃密史
The MT1467 AM/FM Double Tuner Module is designed specifically for high-end automotive radio and entertainment systems. It is optimized to meet the performance, market and pricing demands of automotive customers. To maximize nsitivity and minimize dropouts due to multipath interference, the MT1467 module incorporates one AM tuner and two independent FM tuner ctions to support a high-performance pha diversity function. The 10.7 MHz IF output can interface readily with a dedicated DSP (e.g. Philips SAF 7730) to form a DSP-bad digital AM/FM radio system. While both FM tuners receive the same frequency in “pha diversity” mode, the FM tuners can also be t to diffe
rent frequencies to receive a RDS channel in the background while listening to another station. An AF sample-andhold interface for the external DSP enables inaudible checking of alternative frequencies within the RDS network. The MT1467 module provides a RF AGC with a clod loop control and adjustable thresholds. A keyed AGC function is implemented to prevent receiver densitization due to erroneous AGC respon. The IF AGC is controlled by the external DSP. Furthermore the module features automatic alignment for the tracking filters and the image rejection filters. All tuner functions and parameters can be controlled via a rial bus interface. HD Radio™ (IBOC) capability is optional. Versions for special AM (LW/MW/SW) and FM bands (Europe, USA, Japan) are also available. The MT1467 module is designed specifically for typical automotive operating conditions. It fully complies with RoHS requirements.
