AD6657ABBCZRL

Overview

The AD6657ABBCZRL is a quad intermediate frequency (IF) diversity receiver manufactured by Analog Devices Inc. It features an integrated 11-bit analog-to-digital converter operating at a sampling rate of 200 MSPS. The device supports input frequencies up to 65 MHz and operates within a supply voltage range of 1.7 V to 1.9 V. It is housed in a 144-lead CSPBGA package measuring 10x10 mm, designed for surface-mount installation with an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent IF receiver channels with simultaneous digitization capabilities
• Supports quadrature downconversion and filtering for direct sampling architectures
• Includes programmable gain amplifiers and digital control interfaces for system integration

Applications

• CDMA wireless communication systems
• LTE base station receivers
• W-CDMA infrastructure equipment
• WiMAX network components

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check current availability as supply may be limited. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate package dimensions against design specifications before procurement.

Selection Notes

Evaluate the requirement for four-channel diversity reception versus single-channel alternatives. Consider the 11-bit resolution and 200 MSPS speed against system dynamic range needs. Assess power consumption constraints given the 1.7 V to 1.9 V supply range. Verify compatibility with existing digital baseband processing units for interface integration.

Part Context

This component belongs to the AD6657A series of RF receivers. It is part of Analog Devices' portfolio for wireless infrastructure applications. The device complements other RF front-end solutions by providing high-performance digitization directly after the mixer stage. It is distinct from temperature sensors or voltage references sharing similar numerical prefixes.
