DigitalTune™ consists of high performance RF building blocks.

• Tuneable RF Front-End Filter with integrated wide-band RF Noise-cancelling LNA
• High Linearity LNA with integrated loop-through
• Cascoded Stacked-Mixer
• High Order dual mode ZIF/LIF Channel Filtering and DC Offset Correction
• Low Phase noise self-calibrating Fractional-N Synthesiser

These high performance elements are then optimised with Digital Signal Processing.

• All processing is fully autonomous and therefore transparent to the digital demodulator
• The four key building blocks are configurable with embedded simple sensors and digital signal processing algorithms for real-life optimisation

Using digital signal processing algorithms, DigitalTune™ has a number of distinct benefits. 

• Flexible Re-Configuration: Each part of the RF signal path is optimally configured for the specific requirements of the broadcast transmission 
• Intelligent Parametric Control of all Signal Processing Blocks: The tuner dynamically adjusts the signal path in real time to cope with real world TV channel conditions
• Autonomous System Operation: No user intervention is required to ensure RF performance is optimised at all times
• Technology increasing flexibility: Multi-standard Operation, Fabrication Process Robustness and System Level Customisation
