AD6622: 65 MSPS, QUAD TRANSMIT SIGNAL PROCESSOR (TSP)

Product Description

Designed for multicarrier, multimode transmitters, the AD6622 is part of Analog Devices' SoftCell™ Multicarrier transceiver chipset. It is compatible with the latest TxDAC® digital-to-analog converters including the recently introduced AD9754, 14-bit device. The AD6622 has four identical digital transmit signal processors (TSP) complete with synchronization circuitry and cascadable, wideband channel summation. Each AD6622 channel has three cascaded signal-processing elements: a RAM-programmable Coefficient interpolating Filter (RCF), a Cascaded Integrated Comb (CIC) interpolating filter, and a numerically controlled oscillator (NCO) frequency translator.
