Procurement Notes

Verify RoHS compliance status prior to procurement, as available documentation indicates the AD9876BST may be non-compliant. Confirm the specific manufacturer part number against official Analog Devices catalogs to ensure accuracy. Validate that the 48-LQFP package matches the required board layout. Cross-reference technical datasheets for exact electrical parameters under specified operating conditions before finalizing orders.

Selection Notes

Select this component when a cost-effective, 3.3 V mixed-signal front-end is required for broadband modem applications. Its pin compatibility with the AD9875 allows for potential design flexibility or upgrades within existing architectures. Ensure the application environment supports the specified voltage range and clock frequencies detailed in the official specifications.

Part Context

The AD9876BST belongs to the Analog Devices AD9876 series of analog front-end ICs. It serves as a specialized solution for integrating analog and digital functions in communication hardware. The device is distinct from evaluation boards like the EVAL-AD9878, which are separate tools for testing related technologies.

Replacement Considerations

The AD9876BST is officially documented as pin-compatible with the AD9875. This substitution option should be verified against current availability and specific performance requirements.
