DAC39RFS12ACK

Digital To Analog Converters Overview

The DAC39RFS12ACK is a single-channel, 16-bit Multi-Nyquist Digital-to-Analog Converter (DAC) manufactured by Texas Instruments. It supports a maximum input data rate of 24 GSPS in single-edge sampling mode and 12 GSPS in dual-edge mode. The device features an analog output bandwidth of 12 GHz and integrates four digital up-converters with 64-bit NCO frequency resolution. It utilizes a JESD204C compatible serial interface with up to 16 lanes operating at speeds up to 12.8 Gbps. The component is housed in a 256-ball Flip Chip Ball Grid Array (FCBGA) package measuring 17mm x 17mm with a 1mm pitch.

Digital To Analog Converters Feature Summary

• Integrates four digital up-converters supporting complex baseband I/Q output and direct RF sampling for dual-channel applications.
• Features a fast reconfiguration interface enabling phase-coherent frequency hopping with a 60 ns reconfiguration time.
• Includes internal AC coupling capacitors and SYSREF windowing for automatic timing calibration within the JESD204C interface.

Digital To Analog Converters Applications

• Satellite Communications (SATCOM)
• Phased array antenna systems
• Synthetic Aperture Radar (SAR) exciter
• Wireless communications testers
• Arbitrary waveform generator (AWG)

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'ACK' against the manufacturer's current datasheet to confirm package type and temperature range specifications. Ensure that the required JESD204C lane count and clock frequencies align with the system design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this single-channel variant when only one high-speed RF output path is required. Compare performance metrics such as SFDR and noise floor against the dual-channel DAC39RF12 model if multiple independent outputs are needed. Verify power supply requirements for VDDA18 and VEEAM18 rails during the initial design phase.

Digital To Analog Converters Part Context

This component belongs to the DAC39RF family of high-performance RF DACs from Texas Instruments. It shares architectural similarities with the DAC39RF12 but differs in channel configuration. The 'RFS' designation indicates the single-channel topology, while the '12' denotes the 12/24 GSPS speed class.
