High-speed paging systems that employ M-ary signals are about to enter service.
Sony strongly supports this new service with three IF ICs: the CXA3117N, the CXA3176N, and the CXA3179N.
The CXA3117N, which adopts a comparator system that does not require an A/D converter, and the CXA3179N, which supports AFC, can contribute significantly to parts count reductions and thus reduced production costs.
The CXA3176N implements a high-speed paging system that uses an A/D converter and supports AFC.

■ Low current consumption
   (CXA3117N/CXA3176N/CXA3179N)
■ No A/D converter required in
   comparator system adopted (CXA3117N/CXA3179N)
■ AFC support (CXA3176N/CXA3179N)
■ RSSI dynamic range: 70 dB,
   detector output: 600 mVrms (CXA3176N)
