RX3408

The RX3408 is a low power IF receiver suitable for use as the second IF downconverter in double conversion receiver systems and a serial data input, phase-locked loop IC with programmable input and reference frequency dividers. The RX3408 is well-suited for wireless FM applications and incorporates a quadrature FM demodulator, on-chip audio filter, and a squelch/mute circuit. When combined with a VCO, this IC becomes the core of a very low power frequency synthesizer well-suited for mobile communication applications, e.x. paging systems and family radio service (FRS). There are some features implemented in this IC, including an 18-bit programmable input frequency divider, a terminal for reference oscillator buffer output, as well as stand-by control through programming, and etc. Details are listed in the following.
