AFE7681IABJ

Analog Front End (AFE) Overview

The AFE7681IABJ is a silicon-based RF front-end transceiver manufactured by Texas Instruments. It features four transmit and two receive channels with an operating frequency of 5.2 GHz. The device supports a maximum data rate of 750 Mbps and operates on supply voltages of 1.15 V and 1.85 V. It is housed in a 400-ball FCBGA package suitable for SMD/SMT installation. The component functions within a temperature range of -40°C to +85°C and exhibits humidity sensitivity.

Analog Front End (AFE) Feature Summary

• Integrated 4-transmit, 2-receive RF-sampling transceiver architecture
• Operates at a center frequency of 5.2 GHz with up to 750 Mbps data rate
• Dual voltage operation at 1.15 V and 1.85 V
• Available in a 400-ball FCBGA surface-mount package

Analog Front End (AFE) Applications

• Wireless communication systems requiring RF sampling capabilities
• Test and measurement equipment utilizing wideband signal processing
• Industrial applications compatible with the specified frequency and voltage ranges

Analog Front End (AFE) Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to ensure correct configuration. Confirm that the required quantity aligns with the standard factory packaging unit of 90 units per tray. Check current availability status as production lead times may vary. Ensure handling procedures account for the component's humidity sensitivity classification during storage and assembly.

Analog Front End (AFE) Selection Notes

Select this model when a 4-TX/2-RX channel configuration is required for 5.2 GHz operations. Compare against the AFE7684IABJ if a 2-TX/4-RX topology is needed instead. Ensure the system design accommodates the 1.15 V and 1.85 V power rails. Verify that the PCB layout supports the 400-ball FCBGA footprint and thermal requirements for the -40°C to +85°C operating range.

Analog Front End (AFE) Part Context

The AFE7681IABJ belongs to the AFE7681 series of RF front-ends from Texas Instruments. It shares the same FCBGA-400 package and core technology as other members like the AFE7684IABJ and AFE7444IABJ. The primary distinction lies in the channel count and specific frequency optimization compared to wider-bandwidth variants in the broader AFE family.

Analog Front End (AFE) Replacement Considerations

The AFE7684IABJ serves as a functional alternative within the same series, offering a reversed 2-TX/4-RX channel configuration while maintaining similar package and voltage specifications.
