Product Details

The AD6634 is a two channel (dual) digital Receive Signal Processor (RSP) with four cascaded signal-processing elements: a frequency translator, two fixed-coefficient decimating filters, and a programmable coefficient-decimating filter. A 16-bit parallel output port provides a means of accommodating high data rate outputs such as in WBCDMA applications.

The AD6634 is part of Analog Devices' SoftCellTM Multi-carrier transceiver chipset designed for compatibility with Analog Devices' family of high sample rate IF sampling ADCs (AD6640 / AD6644 12 & 14 bit). The SoftCellTM receiver comprises a digital receiver capable of digitizing an entire spectrum of carriers and digitally selecting the carrier of interest for tuning and channel selection. This architecture eliminates redundant radios in wireless base station applications.

High dynamic range decimation filters offer a wide range of decimation rates. The RAM-based architecture allows easy reconfiguration for multi-mode applications.
