DAC38RF85IAAV

Digital To Analog Converters Overview

The DAC38RF85IAAV is a single-channel, 14-bit Digital-to-Analog Converter (DAC) from Texas Instruments. It supports an ultra-high-speed sample rate of 9 GSPS and features 6x to 24x digital interpolation. The device integrates a 6 GHz and 9 GHz Phase-Locked Loop (PLL) for clock generation. It utilizes the JESD204B interface for data input and operates within a temperature range of -40°C to +85°C. The component is housed in a 144-lead FCBGA package.

Digital To Analog Converters Feature Summary

• Integrates dual-band PLL supporting 6 GHz and 9 GHz frequencies for flexible clocking architectures.
• Provides high-resolution 14-bit conversion with up to 9 GSPS sampling capability.
• Includes broadband digital upconverter with variable interpolation ratios from 6x to 24x.

Digital To Analog Converters Applications

• Point-to-point microwave radio systems
• Software-defined radio (SDR) platforms
• Direct RF synthesis applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure compatibility with JESD204B link configurations and power supply requirements during sourcing. Confirm package authenticity and handling procedures due to moisture sensitivity classification.

Digital To Analog Converters Selection Notes

Select this model when a single-channel architecture suffices for the design. Compare against the dual-channel DAC38RF83IAAV if two independent RF paths are required. Evaluate the DAC38RF87IAAV or DAC38RF90IAAV if different interpolation ranges or channel counts better match system bandwidth needs.

Digital To Analog Converters Part Context

This component belongs to the DAC38RF8x family of high-performance RF DACs. It shares architectural similarities with other members like the DAC38RF80 and DAC38RF82 but differs in channel count and specific PLL tuning ranges. It is designed for direct RF transmission without intermediate frequency stages.

Digital To Analog Converters Replacement Considerations

The DAC38RF85IAAR is the reel-packaged version of the same die. For dual-channel requirements, consider the DAC38RF83IAAV. Verify that any substitute maintains the 144-FCBGA footprint and JESD204B interface compatibility.
