General Description

The AD7002 is a complete low power, two-channel, input/ output port with signal conditioning.

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.
