AD6643BCPZRL7-200

Overview

The AD6643BCPZRL7-200 is a dual intermediate frequency (IF) receiver integrated circuit manufactured by Analog Devices Inc. It features two independent channels, each capable of sampling at rates up to 200 MSPS. The device integrates high-speed analog-to-digital converters with digital downconverters and quadrature demodulators. It operates within a supply voltage range of 1.71 V to 5.5 V for digital logic and supports analog supplies from -33 V to 0 V or 5 V to 33 V. The component is housed in a 64-lead LFCSP-VQ package measuring 9x9 mm and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel architecture supporting simultaneous signal processing
• Integrated digital downconversion and quadrature demodulation
• High-speed sampling capability up to 200 MSPS per channel
• Flexible power supply options for mixed-signal operation

Applications

• CDMA base station receivers
• CDMA2000 communication systems
• LTE infrastructure equipment
• WiMAX network components

Procurement Notes

Verify the specific suffix RL7 indicates tape-and-reel packaging configuration when sourcing. Confirm that the -200 designation corresponds to the 200 MSPS speed grade required for your system timing constraints. Ensure compatibility with the 64-lead LFCSP-VQ footprint during PCB layout review. Check current availability status as supply levels may fluctuate due to manufacturing allocations.

Selection Notes

Select this component when dual-channel IF reception with high sample rates is required. Compare against single-channel alternatives if only one path is needed. Verify that the integrated digital downconverter meets your baseband processing requirements without additional external DSP resources. Consider thermal management solutions given the power consumption characteristics of high-speed ADCs in compact packages.

Part Context

This part belongs to the AD6643 family of high-performance RF receivers designed for wireless infrastructure. It complements evaluation boards like the EVAL-AD6643-200EBZ for development purposes. The device represents Analog Devices' solution for simplifying front-end design in multi-standard radio applications by combining analog and digital processing on a single chip.
