AD6655ABCPZ-125

Overview

The AD6655ABCPZ-125 is a mixed-signal intermediate frequency receiver manufactured by Analog Devices Inc. It integrates dual 14-bit analog-to-digital converters and a broadband digital downconverter within a single package. The device supports sample rates up to 125 MSPS, accommodating IF frequencies from 0 Hz to 450 MHz. It operates on supply voltages ranging from 1.7 V to 1.9 V for the core logic and 3.6 V maximum for I/O. The component is housed in a 64-pin LFCSP-VQ (9x9 mm) package, designed for compact wireless infrastructure applications requiring high linearity and low power consumption.

Feature Summary

• Integrates dual 14-bit ADCs with a broadband digital downconverter for direct IF sampling
• Supports CDMA, EDGE, and GSM standards through flexible IF diversity reception
• Enables small form factor designs by combining RF front-end processing with digital conversion

Applications

• CDMA base station receivers
• EDGE network infrastructure
• GSM communication systems

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status via official documentation prior to integration. Ensure storage conditions meet humidity sensitivity requirements specified in the datasheet. Validate pinout compatibility with target PCB layout using the provided footprint data. Request lot traceability information to maintain quality assurance standards during procurement.

Selection Notes

Select this model when designing systems requiring simultaneous dual-channel signal processing at 125 MSPS. Consider the 14-bit resolution for applications demanding high dynamic range in IF stages. Evaluate the 0 Hz to 450 MHz input range against specific carrier frequencies. Assess thermal performance within the -40°C to +85°C operating window. Compare power consumption metrics against alternative receivers to optimize system efficiency.

Part Context

The AD6655 series represents Analog Devices' solution for compact wireless infrastructure. This specific variant targets multi-standard base stations where space and power are critical constraints. It replaces discrete ADC and DDC implementations, reducing bill of materials complexity. The family includes variants supporting different sample rates, with the -125 suffix denoting the 125 MSPS capability.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications before considering any substitute part numbers.
