Baseband

The baseband architecture is a combination ofthe HD945 and Santeri HD914 baseband architecture. The baseband differ from the HD945 phone in not having a slide and roller. The system specific MCU and DSP are integrated into one ASIC, called the MAD2WD1 Compared to MAD2PR1 from HD945 it holds the following changes Flexpool synthEna2X added to flexpool. The ARM on the part is able to run at 26MHz, a PLL is included to double the frequency. A new concept in this product is that only LCD, earpiece,...
