AD6643BCPZ-250

Overview

The AD6643BCPZ-250 is an 11-bit, dual-channel intermediate frequency (IF) receiver manufactured by Analog Devices Inc. It supports sampling rates up to 250 MSPS and is housed in a 64-LFCSP-VQ package measuring 9x9 mm with a height of 0.83 mm. The device operates on a single 1.8 V supply voltage and features differential inputs. Key performance metrics include a signal-to-noise ratio of 72 dB, differential nonlinearity of +/- 0.75 LSB, integral nonlinearity of +/- 3.5 LSB, and gain error of +/- 4% FSR. Power dissipation is rated at 785 mW, with an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture designed for multi-antenna systems
• Integrated pipeline ADC structure for high-speed data conversion
• Supports parallel and SPI interface types
• LVDS output format

Applications

• CDMA systems
• CDMA2000 applications
• LTE infrastructure
• WiMAX implementations

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels due to limited supply status. Confirm RoHS compliance details prior to integration. Ensure proper handling procedures are followed as the device exhibits humidity sensitivity. Validate that the specific suffix matches the required sampling rate specifications for the target design implementation.

Selection Notes

Select this component when designing systems requiring high dynamic range performance with low power consumption and small physical footprint. It is suitable for applications demanding dual-channel IF reception capabilities. Consider the 11-bit resolution and 250 MSPS speed against system requirements for linearity and noise performance.

Part Context

This part belongs to the AD6643 series of RF receivers. It is distinct from the AD9643, which is a 14-bit ADC, and the AD6643-200EBZ evaluation board. The AD6643BCPZ-250 specifically targets telecom applications supporting multiple antenna configurations within a compact surface-mount package.
