AD6676BCBZRL

Overview

The AD6676BCBZRL is a wideband intermediate frequency (IF) receiver subsystem manufactured by Analog Devices Inc. It integrates a continuous-time bandpass sigma-delta analog-to-digital converter (CTBPSD ADC) to digitize IF signals within a bandwidth of up to 160 MHz. The device operates on input frequencies ranging from 70 MHz to 450 MHz and supports a maximum operating temperature of +85°C with a minimum of -40°C. It functions within a supply voltage range of 1.1 V to 2.5 V, drawing a typical operating current of 368 mA. Key electrical specifications include a noise figure of 13 dB. The component is housed in an 80-contact WLCSP package designed for surface mount installation.

Feature Summary

• Integrates highly programmable analog filtering functionality directly into the receiver chain.
• Utilizes continuous-time bandpass sigma-delta topology for high dynamic range signal conversion.
• Provides flexible frequency planning capabilities through wideband digital output.

Applications

• Multimode cellular infrastructure equipment
• Point-to-point microwave communication systems
• General purpose instrumentation devices

Procurement Notes

Verify component authenticity and datasheet revisions prior to integration. Confirm that the specific WLCSP-80 package variant matches your PCB footprint requirements. Ensure power supply rails are stable within the 1.1 V to 2.5 V range to maintain specified noise performance. Check for any recent production change notices regarding material composition or pinout definitions.

Selection Notes

Select this component when designing systems requiring direct digitization of wideband IF signals without external mixers. The integrated programmable filter reduces the need for discrete analog components. Evaluate thermal management needs due to the 368 mA operating current. Consider the 80-contact WLCSP package size constraints during layout design.
