摘要:
A cellular telephone IC includes a baseband processing module, an RF section, an audio codec, a keypad interface, a memory interface, and a display interface. The baseband processing module and RF section function to convert an outbound voice signal into an outbound RF voice signal, to convert an inbound RF voice signal into an inbound voice signal, to convert outbound data into an outbound RF data signal, and to convert an inbound RF data signal into inbound data. The audio codec section converts inbound analog voice signals into the inbound voice signals and converts the outbound voice signals into outbound analog voice signals. The keypad interface produces the outbound data based on received inputs. The display interface provides the inbound data to an off-chip display.
