ATR4255P

Electrostatic sensitive device.

Observe precautions for handling.

1. Description

The ATR4255P 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

ATR4256, an automatically aligned high-performance AM/FM tuner can be built.

These ICs are designed for highly sophisticated car radio applications.
