Low-Power Multiband Broadcast Radio IP Features Description Catena’s multiband radio front-end IP is a fully integrated alignment-free turn-key SoC solution for analog and digital radio broadcast reception. It receives analog FM and AM as well as digital radio broadcasts DAB, HD, DRM30+ which are applicable in the L-, VHF3-, VHF2-, SW-, MW- and LW-bands. The IP supports 50/75 Ω terminated antenna inputs (DAB-L, DAB3, FM), a 40 cm telescopic antenna input (DAB-3, FM, SW) and a magnetic ferroceptor input (MW, LW). This MW/LW ferrocepter antenna is fully tuned internally, but the IP also provides a tune DAC functionality for varactor tuning support (e.g. to tune resonating antennas). For digital broadcast standards, the IP interfaces the received signal at baseband together with front-end AGC information to an external decoder subsystem. Analog broadcast standards (AM/FM) are completely processed inside the radio IP (incl. RDS; DARC optional). The demodulated audio signal is available either at the digital I2S interface or as analog audio out viw the optional high quality stereo DAC. The multi standard receiver architecture is optimized for modern CMOS technologies and shows best in class performance with excellent sensitivity and signal handling capabilities.
