NXP Semiconductors developed the TEA5990¡Xsaid to be the world's smallest highly-integrated FM stereo radio IC with R(B)DS functionality. The FM-RDS chip sets a new standard in radio performance, with better channel separation, sensitivity, high selectivity and clear sound. The TEA5990 inches ahead of competitive offerings by using a command-based interface to simplify software development, making system integration easy and quick to enable OEMs to drive higher attach rates for FM radio in portable devices.
The 2.56x2.56mm TEA5990 FM radio IC allows OEMs to implement a complete radio solution without external components, requiring less than 15mm² of board space. NXP's FM-radio IC also enables quick integration and flexible design-ins by supporting the I2C-bus and the SPI-bus (three- or four-wire format), while a digitally controlled algorithm facilitates seamless coexistence with GSM, Bluetooth, Wi-Fi and WiMAX. The TEA5990 also offers better reception quality over a wide tuning range (70MHz to 108MHz, including the 70MHz China band) with Stereo Noise Cancelling (SNC) as well as built-in Auto Search and Store for up to 32 channels with dynamic adjacent channel suppression.
