Controllers Procurement Notes

Verify the specific ordering suffix against current Texas Instruments documentation to confirm package type and environmental compliance. Confirm that the component meets the required operating temperature specifications for the intended deployment environment before finalizing orders.

Controllers Selection Notes

Select this controller when designing systems requiring dedicated hardware support for DV formatted data over IEEE 1394 networks. Ensure the host processor architecture matches the supported microprocessor interface modes. Verify that the system design accommodates the necessary 3.3 V power supply requirements and thermal dissipation for the LQFP package.

Controllers Part Context

This component belongs to the DVLynx family of link-layer controllers developed by Texas Instruments. It serves as a specialized interface between host processors and IEEE 1394 physical layers, focusing on efficient handling of digital video streams. The device simplifies protocol implementation by offloading packetization and formatting tasks from the main CPU.

Controllers Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Generic replacements may lack the specific bulky data FIFO architecture or DV formatting capabilities required for seamless integration.
