NXP TEA5990 FM-RDS Stereo Radio IC

NXP Semiconductors recently launched the TEA5990, which is the world’s smallest highly-integrated FM stereo radio IC with R(B)DS functionality. NXP’s FM-RDS chip sets a new standard in radio performance, with better channel separation, best-in-class sensitivity, very 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 NXP TEA5990 FM-RDS stereo radio IC has a guide price of 70 cents (US) for 100K quantities.

Packaged in a 2.56×2.56mm size, the 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 (3- or 4-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 (70 to 108 MHz, including the 70-MHz 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.
