Digital Radio

Digital radio is taking the old broadcast medium into the digital age. Digital radio is almost immune to the sort of interference that can make listening to todays conventional AM or FM radio less than satisfying.

Design Considerations

Digital radio is taking the old broadcast medium into the digital age with crystal-clear music, hundreds of new stations, on-demand radio, surround sound, rewind radio and more. TI with its strategic partners provide ready-to-go modules and reference designs for digital radio applications such as: automotive, home, portable and home hi-fi applications.

TI and its strategic partners, RadioScape and iBiquity, provide low-risk, cost-effective solutions for a quickly changing digital radio market.

TIs Solution includes:

Analog Front End - built around a high-speed ADC including Low-Noise Amplifiers (LNA), frequency synthesizers, and high-speed Op-Amps. The LNA boosts the RF signal from the antenna. The frequency syntahesizer generates a Local Oscillator (LO) signal that is mixed with the RF input to form the IF signal. The high-speed ADC converts the IF signal into digital samples.

Digital Down Converter (DDC) - performs down conversion, digital mixer, and decimation filtering to provide baseband I and Q output signals.

DSP/CPU - performs I/Q demodulation and outputs digital audio and data. The CPU controls the user interface, bus interface, and network interface.

Analog Output - uses stereo DACs and audio power Amps to send analog audio output to the speakers.

Bus/Network Interface - transfers data through high-speed parallel bus on the back plane (PCI, VMEbus) or high-speed ethernet.

Clock Source - provides clocking for different data acquisition options and modes.

Power Conversion - converts input power to run various functional blocks.
