Product Summary

The AD6623ASZ is a kind of 4-channel Transmit Signal Processor (TSP). It creates high bandwidth data for Transmit Digital-to-Analog Converters (TxDACs) from baseband data provided by a Digital Signal Processor (DSP). The device 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.
