Dual-tuner DVB-T ExpressCard 54 reference design for notebooks
( 01 Sep 2006 )
The MicMamba 2D-XC from Micronas is a dual-tuner DVB-T ExpressCard 54 reference design for notebook computers. With two independent tuners on a single card, notebook users can watch one program while recording another, enabling the notebook to double as a portable TV or full media center. The card can also combine the signals from both tuners to increase signal quality while moving or in marginalreception areas. This capability, commonly called “antenna diversity”, is based on the patented ‘Maximum Ratio Combining’ technology licensed from Rohde and Schwarz.
MicMamba 2D-XC uses the DRX 3976D COFDM demodulator and exceeds all requirements of the NorDig-Unified v1.0.2 Receiver Specification. It allows a single design to be compatible with all DVB-T standards worldwide. The card also features the nGene APB 7202A PCI Express controller from Micronas, and a MicroTuner MT2060 digital TV tuner from Microtune.
