AD6633BBC

Overview

The AD6633BBC is a multi-channel, wide-bandwidth digital transmit signal processor (TSP) featuring the VersaCREST crest reduction engine. Designed for up-conversion applications, it supports CDMA2000, Cellular, EDGE, GPRS, and GSM standards. The device operates at 125 MSPS with supply voltages of 1.8 V and 3.3 V. It is housed in a 196-CSPBGA package measuring 15x15 mm. This component is classified as obsolete.

Feature Summary

• Integrates VersaCREST crest reduction engine for signal optimization
• Supports multiple wireless standards including WCDMA and GSM
• Provides digital transmit signal processing capabilities

Applications

• CDMA2000 base station transmitters
• WCDMA digital up-conversion systems
• EDGE and GPRS infrastructure equipment
• GSM cellular network transmission modules

Procurement Notes

This product is officially marked as obsolete by Analog Devices Inc., with discontinuation notifications dated February 7, 2020. Verify current availability through authorized distributors or secondary markets, as new manufacturing is no longer supported. Ensure compatibility with existing designs before sourcing replacement units.

Selection Notes

Select this component only for legacy system maintenance or specific backward-compatible designs requiring 125 MSPS TSP functionality. Evaluate alternative modern processors if new development is planned, given the obsolete status. Confirm package dimensions and voltage requirements match the target PCB layout and power architecture.

Part Context

The AD6633 belongs to the AD6633 series of RF ICs designed for wireless infrastructure. It serves as a digital up-converter within the Analog Devices portfolio, distinct from receive-focused models like the AD6634. The BBC suffix indicates specific performance characteristics aligned with WCDMA and multi-mode cellular applications.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided documentation. Consider evaluating the AD6634 for receive-side integration or consulting Analog Devices for current generation TSP alternatives suitable for modern multi-mode base stations.
