DAC39RF10ACK

Digital To Analog Converters Overview

The DAC39RF10ACK is a dual-channel, 16-bit direct digital synthesizer and multi-Nyquist digital-to-analog converter manufactured by Texas Instruments. It operates with a maximum clock frequency of 10.24 GHz and supports an analog output bandwidth of 12 GHz. The device features four integrated digital up-converters (DUCs) with interpolation ratios ranging from 1x to 256x, and includes 64-bit resolution numerically controlled oscillators (NCOs). It utilizes a JESD204C compatible serial interface with up to 16 lanes at speeds reaching 12.8 Gbps per lane. The component is housed in a 256-ball Flip Chip Ball Grid Array (FCBGA) package measuring 17 mm x 17 mm.

Digital To Analog Converters Feature Summary

• Integrates four digital up-converters supporting complex baseband processing and direct RF sampling applications.
• Features a high-speed JESD204C SerDes interface with internal AC coupling capacitors for deterministic latency.
• Includes a fast reconfiguration interface enabling phase-coherent frequency hopping within 60 nanoseconds.
• Supports SYSREF windowing for automatic timing calibration across multiple synchronized devices.

Digital To Analog Converters Applications

• Satellite communications (SATCOM)
• Phased array antenna systems
• Synthetic aperture radar (SAR) exciter
• Wireless communications testers
• Arbitrary waveform generators (AWG)

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'ACK' against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Ensure that the design accounts for the required supply voltage ranges and thermal dissipation characteristics specified in the electrical characteristics section before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel architecture with 16-bit resolution is required for direct RF sampling or complex baseband generation. Compare performance metrics such as spurious-free dynamic range and noise floor against single-channel alternatives like the DAC39RFS10 if only one output path is needed. Evaluate the need for the specific 10.24 GHz clock rate versus higher-speed variants in the family.

Digital To Analog Converters Part Context

This device belongs to the DAC39RF10 family, which also includes the single-channel DAC39RFS10 and higher-speed variants like the DAC39RF12. All members share similar architectural features but differ in channel count and maximum sample rates. The DAC39RF10 specifically targets applications requiring two independent high-frequency outputs with precise phase coherence.

Digital To Analog Converters Replacement Considerations

The DAC39RFS10 serves as a single-channel alternative within the same family. For higher throughput requirements, the DAC39RF12 offers increased sample rates but requires verification of interface and pin compatibility.
