1. Description
The ATR4258 is a highly integrated AM/FM front-end circuit manufactured using
Atmel ’s advanced BICMOS technology. It represents a complete, automatically
adjustable AM/FM front end, containing a double-conversion system for FM and an
up/down-conversion receiver for AM with IF1 = 10.7 MHz and IF2 = 450 kHz. The
front end is suitable for digital or analog AF-signal processing. Together with the PLL
U4256BM, an automatically aligned high-performance AM/FM tuner can be built.
These ICs are dedicated for highly sophisticated car radio applications.
