Maxim’s remote tuner architecture is scalable—you can easily add additional tuners for background scan and phase diversity without changing the head unit design. Learn more about Maxim’s Automotive Solutions at www.maximintegrated.com/auto
Traditional automotive radio head units are complex as they must accommodate multiple tuners and require multiple cables from the antennas. Heat generated by the concentration of electronics may require the use of heatsinks and degrade reliability. The received analog signals pick up noise as they travel from the antenna to the head unit. Maxim’s remote tuner architecture simplifies head unit design while improving radio signal quality and reducing cost, weight, and power consumption. Tuners are located close to the antennas. Received signals are serialized and sent to the head unit over a single coax cable, which also provides I2C communication and power. With Maxim’s RF to Bits® radio tuner IC, the baseband processing can be done on the Renesas R-Car H3 SoC using software. This software-defined radio (SDR) approach enables flexible implementations by eliminating the need for a dedicated baseband processor. Any worldwide radio standard can be supported via a change in the software.
