Product Summary
The AD6623AS is a kind of 4-channel Transmit Signal Processor (TSP). The AD6623AS creates high bandwidth data for Transmit Digital-to-Analog Converters (TxDACs) from baseband data provided by a Digital Signal Processor (DSP). The AD6623AS synthesizes multicarrier and multistandard digital signals to drive these TxDACs. The device has four identical digital TSPs complete with synchronization circuitry and cascadable wideband channel summation. It is designed for Cellular/PCS Base Stations, Micro/Pico Cell Base Stations, Wireless Local Loop Base Stations, Multicarrier, Multimode Digital Transmit, Phased Array Beam Forming Antennas and Software Defined Radio.
