65 MSPS, Quad Transmit Signal Processor (TSP)

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.

* 65 MSPS Wideband Input and Output (18-Bit) * Four Independent Digital Transmitters in a Single Package * Separate 3-Wire Serial Data Input for Each Channel * Programmable Interpolating RAM Coefficient Filters * Programmable IF For Each Channel * JTAG Boundary Scan
