Description

The CXA1742Q is an analog cellular(AMPS) FM IF IC which include an IF filter.

Features

• Include a ceramic filter function, which is normally

mounted externally.

• Quadrature detection discriminator function.

• This IC has almost all IF functions and is ideal for

reduction in set size because of few external parts

required.

• Channel filter conforming to the AMPS standard.

• Wide operating voltage range (2.7 V to 3.6 V) and

low current consumption (Icc=10 mA (typ.) when

Vcc= 3 V).

• Wide range and excellent temperature

characteristics for the RSSI (receiving signal

strength indicator).

Applications

Ideally suited for cellular phones, particularly handheld sets.
