DAC38RF90IAAV

Digital To Analog Converters Overview

The DAC38RF90IAAV is a dual-channel, 14-bit digital-to-analog converter (DAC) from Texas Instruments. It supports a maximum sample rate of 9 GSPS and includes 12x to 24x interpolation filters. The device integrates a 6 GHz and 9 GHz phase-locked loop (PLL) for clocking flexibility. It utilizes a JESD204B interface and operates within an industrial temperature range of -40°C to 85°C. Packaged in a 144-FCBGA, it consumes approximately 3800 mW with a typical SFDR of 72 dB.

Digital To Analog Converters Feature Summary

• Integrates high-speed 6 GHz and 9 GHz PLLs for flexible clocking schemes.
• Includes programmable interpolation filters ranging from 12x to 24x.
• Supports JESD204B serial data interface for reduced pin count.

Digital To Analog Converters Applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Ensure the ordering part number matches the required revision level. Confirm RoHS compliance status through the manufacturer's current datasheet or certification documents before finalizing procurement specifications.

Digital To Analog Converters Selection Notes

Select this component when high spectral purity at multi-gigahertz output frequencies is required. The integrated PLL reduces external clocking complexity compared to non-PLL variants. Verify that the system's FPGA can support the necessary JESD204B lane configuration and interpolation settings for the target application bandwidth.

Digital To Analog Converters Part Context

This device belongs to the DAC38RF family, designed for direct RF synthesis applications. It shares architectural similarities with the DAC38RF80 and DAC38RF93 but differs in specific PLL frequency ranges and feature sets. It serves as a high-performance alternative to lower-speed DACs in advanced wireless infrastructure designs.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same series include the DAC38RF93IAAV. Evaluate differences in PLL specifications and interpolation filter configurations when considering cross-model replacements to ensure compatibility with existing system clocking architectures.
