Un altro chip con DSP

Ancora DSP integrato in un chip con consumi e dimensioni ridottissimi per la ricezione dell'FM con RDS. Questa volta il "colpevole" è NXP, azienda indipendente nata da una costola di Philips. Il chip si chiama TEA5990 e permette di realizzare radio FM/RDS con copertura da 70 a 108 MHz, in soli 2 millimetri e mezzo di lato. Con tutta questa disponibilità di silicio DSP per le modulazioni analogiche, chi penserà a fabbricare ricevitori digitali?

NXP Launches Highly-Integrated FM-RDS Stereo Radio IC

3/3/2008 Eindhoven, The Netherlands -- NXP Semiconductors, the independent semiconductor company founded by Philips, launched the company’s smallest highly-integrated FM stereo radio IC with R(B)DS functionality, the TEA5990. 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.
Packaged in a 2.56 x 2.56 mm 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.
“NXP’s TEA5990 helps manufacturers address the burgeoning demand for FM radio in low-cost handsets, by offering a low-cost solution that can be designed-in with complete ease,” said Timothy Wang, Marketing Manager for Connectivity and Broadcast Products, Mobile & Personal Business at NXP Semiconductors. “With consumers becoming more mobile globally, NXP’s chip with integrated RDS functionality makes it easier for users receive important announcements such as traffic updates, allowing any necessary journey changes to be made, while they listen to radio.”
“As the personal media player market grows to adopt FM functionality as a given standard, A-MAX is leveraging NXP’s TEA5990 FM-RDS chip to combine location-based service on PMPs,” said Frank Chang, General Manager for Marketing at A-MAX Technology. “With NXP’s TEA5990, A-MAX is poised to offer optimized production-ready reference designs to OEMs.”
NXPs’ FM-RDS stereo radio IC, TEA5990 will begin mass production end of Q1 2008
