The device is used as a baseband digitization subsystem, performing signal conversion between the DSP and the IF/RF sections in the Pan-European telephone system (GSM).
The transmit path consists of an onboard digital modulator, containing all the code necessary for performing Gaussian Minimum Shift Keying (GMSK), two high accuracy, fast DACs with output reconstruction filters.
The receive path is composed of two high performance sigma-delta ADCs with digital filtering.
