PRODUCT DESCRIPTION
The AD6624 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.
AD6624
The AD6624 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 AD6624 is compatible with standard ADC converters such
as the AD664x, AD9042, AD943x, and the AD922x families of
data converters. The AD6624 is also compatible with the AD6600
Diversity ADC, providing a cost and size reduction path.
