AD6655ABCPZ-150

Overview

The AD6655ABCPZ-150 is a mixed-signal intermediate frequency (IF) diversity receiver manufactured by Analog Devices Inc. It integrates dual 14-bit analog-to-digital converters (ADCs) operating at a maximum sampling rate of 150 MSPS. The device features a wideband digital downconverter (DDC) with decimation filters and a 32-bit complex numerically controlled oscillator (NCO). It supports IF input frequencies up to 70 MHz when sampled at 150 MSPS. Power specifications include a 1.8 V analog supply and CMOS or LVDS output interfaces. The component is housed in a 64-lead LFCSP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual 14-bit ADCs with high channel isolation for diversity reception
• Includes wideband digital downconversion with programmable decimation filtering
• Supports flexible digital output interface options including CMOS and LVDS
• Provides fast overrange detection and signal monitoring capabilities

Applications

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

Procurement Notes

Verify the specific suffix '150' to confirm the 150 MSPS sampling rate variant, as other suffixes like '80', '105', or '125' denote different performance tiers. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the LFCSP-64 footprint matches the design layout exactly. Check for current production status updates, as availability may vary by region.

Selection Notes

Select this part when a high-resolution, low-power IF receiver with integrated digital processing is required. The 150 MSPS speed suits applications demanding higher instantaneous bandwidth compared to lower-speed variants. Evaluate power consumption against system constraints, noting the 1.8 V analog supply requirement. Consider the small form factor of the LFCSP package for space-constrained designs.

Part Context

This component belongs to the AD6655 family of IF diversity receivers from Analog Devices. The family shares a common architecture but varies in maximum sampling rates, indicated by suffixes such as -80, -105, -125, and -150. The AD6655 series is designed for cost-effective, compact wireless communication solutions requiring high dynamic range and digital flexibility.

Replacement Considerations

Direct substitutes within the same family include AD6655ABCPZ-80, AD6655ABCPZ-105, and AD6655ABCPZ-125, which offer lower sampling rates. Verify pin compatibility and software configuration differences when migrating between these variants.
