General Description
AD6624A General Description
The AD6624A is a four-channel (quad) 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.
The AD6624A(R) is part of Analog Devices' SoftCell multicarrier transceiver chipset designed for compatibility with Analog Devices' family of high sample rate IF sampling ADCs (AD6640/AD6644 12- and 14-bit). The SoftCell 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 multimode applications.
The decimating filters remove unwanted signals and noise from the channel of interest. When the channel of interest occupies less bandwidth than the input signal, this rejection of out-of-band noise is called "processing gain." By using large decimation factors, this "processing gain" can improve the SNR of the ADC by 30 dB or more. In addition, the programmable RAM coefficient filter allows antialiasing, matched filtering, and static equalization functions to be combined in a single, cost- effective filter.
The AD6624A is compatible with standard ADC converters such as the AD664x, AD9042, AD943x and the AD922x families of data converters. The AD6624A is also compatible with the AD6600 Diversity ADC, providing a cost and size reduction path.
