AFE7953IALK

RF Transceiver ICS Overview

The AFE7953IALK is a two-transmit, two-receive RF-sampling analog front-end manufactured by Texas Instruments. It operates within a frequency range of 600 MHz to 12 GHz and supports a maximum data rate of 29.5 Gb/s. The device integrates 12-GSPS digital-to-analog converters and 3-GSPS analog-to-digital converters. It functions with supply voltages between 900 mV and 1.85 V and withstands operating temperatures from -40°C to +85°C. The component is housed in a 400-ball FCBGA package measuring 17 mm x 17 mm.

RF Transceiver ICS Feature Summary

• Integrates high-speed 12-GSPS DACs and 3-GSPS ADCs for direct RF sampling capabilities
• Supports multiband operation across the 600 MHz to 12 GHz spectrum
• Provides a compact two-transmit, two-receive architecture

RF Transceiver ICS Applications

• Cellular infrastructure systems
• LTE network implementations
• Multiband radio frequency transceivers

RF Transceiver ICS Procurement Notes

Verify the specific suffix ALK to confirm the FCBGA-400 package type and temperature grade. Confirm moisture sensitivity handling requirements during assembly. Ensure compatibility with the required 900 mV to 1.85 V power rails. Validate that the 12-GSPS and 3-GSPS data rates meet system throughput needs. Check for RoHS compliance status as indicated in official documentation.

RF Transceiver ICS Selection Notes

Select this component when a dual-channel RF-sampling solution is required for frequencies up to 12 GHz. The integrated high-speed converters reduce external component count compared to discrete architectures. Consider the FCBGA-400 footprint constraints during PCB layout. Evaluate thermal management capabilities given the operating temperature range. Compare against other AFE79xx variants if different channel counts are needed.

RF Transceiver ICS Part Context

This part belongs to the AFE7953 family of RF-sampling analog front-ends designed for wireless infrastructure. It shares architectural similarities with other devices in the series but offers a specific two-transmit, two-receive configuration. The ALK suffix denotes the specific ball grid array package variant used for surface mount applications.

RF Transceiver ICS Replacement Considerations

The AFE7953IABJ is a documented alternative within the same product family, offering identical electrical specifications but utilizing a BGA-400 package instead of the FCBGA-400.
