Description

The CXA1741Q is an analog cellular(TACS/NTACS) FM IF IC which incorporates an IF filter.

Features

• Incorporates 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.

• The built-in filter permits mode changeover between TACS and NTACS.

• 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.
