Four-Channel, 100 MSPS Digital

Receive Signal Processor (RSP)

AD6624A

The AD6624A 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.

FEATURES

100 MSPS Wideband Inputs (14 Linear Bits Plus 3 RSSI)

Dual High-Speed Data Input Ports

Four Independent Digital Receivers in Single Package

Digital Resampling for Noninteger Decimation Rates

Programmable Decimating FIR Filters

Programmable Attenuator Control for Clip Prevention

and External Gain Ranging via Level Indicator

Flexible Control for Multicarrier and Phased Array

3.3 V I/O, 2.5 V CMOS Core

High dynamic range decimation filters offer a wide range of

decimation rates. The RAM-based architecture allows easy

reconfiguration for multimode applications.

User-Configurable Built-In Self-Test (BIST) Capability

JTAG Boundary Scan

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.

APPLICATIONS

Multicarrier, Multimode Digital Receivers GSM, IS136,

EDGE, PHS, IS95

Micro and Pico Cell Systems

Wireless Local Loop

Smart Antenna Systems

Software Radios

In-Building Wireless Telephony

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.

PRODUCT 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.
