DDS39RFS10ACL

Overview

The Texas Instruments DDS39RFS10ACL is a specialized direct digital synthesizer featuring a single-channel, 16-bit multi-Nyquist DAC core. It supports sampling rates from 10.24 GSPS to 20.48 GSPS with an analog output bandwidth of 12 GHz. The device integrates four digital upconverters (DUCs) with interpolation factors of 4x, 6x, 8x, and 12x, alongside a 64-bit numerically controlled oscillator (NCO). It utilizes a JESD204C serial interface with two receiver pairs operating at speeds up to 12.8 Gbps. Power supply requirements are 0.95V to 1.05V and 1.71V to 1.89V, housed in a 256-FCBGA package.

Feature Summary

• Single-channel architecture optimized for complex baseband or direct RF sampling applications
• Integrated high-resolution NCO enabling phase-coherent frequency hopping
• Flexible digital upconversion with multiple interpolation options for signal processing
• JESD204C compliant interface supporting deterministic latency and multi-device synchronization

Applications

• Satellite communication (SATCOM) systems requiring precise frequency synthesis
• Phased array antenna beamforming networks
• Synthetic aperture radar (SAR) signal generation
• Wireless communication test equipment

Procurement Notes

Verify the specific suffix 'ACL' against official datasheets to confirm package type and temperature range. Ensure compatibility with JESD204C lane configurations and power sequencing requirements during integration. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this model when a single high-speed channel is sufficient for I/Q generation or direct RF sampling. Compare against the dual-channel DDS39RF10 series if independent dual-path processing is required. Evaluate the 12 GHz output bandwidth against system carrier frequency needs to ensure adequate Nyquist zone coverage.

Part Context

This component belongs to the DDS39RFS10 family of direct digital synthesizers from Texas Instruments. It shares architectural similarities with the dual-channel DDS39RF10 but provides a single-channel configuration. The series targets high-performance RF applications demanding wide instantaneous bandwidth and high spectral purity.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternative vendors, particularly regarding JESD204C compatibility and pinout alignment.
