DDS39RF10ACL

Overview

The Texas Instruments DDS39RF10ACL is a specialized direct digital synthesizer featuring a 16-bit, two-channel 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 includes four integrated digital upconverters (DUCs) and a 64-bit numerically controlled oscillator (NCO). It utilizes a JESD204C 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. The component operates within a temperature range of -40°C to +85°C and is housed in a 256-FCBGA package measuring 17x17 mm.

Feature Summary

• High-speed multi-Nyquist DAC architecture enabling direct RF signal generation up to 12 GHz
• Integrated complex baseband processing via dual-channel DUCs for I/Q outputs
• JESD204C compliant serial interface supporting deterministic latency and multi-device synchronization
• Fast reconfiguration capability allowing phase-coherent frequency hopping with minimal delay

Applications

• Satellite communication (SATCOM) systems requiring high-frequency agility
• Phased array antenna beamforming networks
• Synthetic aperture radar (SAR) signal excitation
• Wireless communication test equipment generating wideband signals

Procurement Notes

Verify the specific suffix 'ACL' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure that the 256-FCBGA package dimensions and thermal dissipation parameters align with the PCB layout constraints. Confirm that the required power supply voltages are stable within the specified tolerances during operation.

Selection Notes

Select this component when a two-channel output is required for complex baseband or direct RF sampling applications. Compare it against the single-channel DDS39RFS10 variant if only one output path is needed. Evaluate the system's need for 16-bit resolution versus lower-resolution alternatives to balance performance and cost. Consider the 12.8 Gbps interface speed compatibility with the host processor's JESD204C controller capabilities.

Part Context

This part belongs to the DDS39RF(S)10 series of direct digital synthesizers from Texas Instruments. The series shares a common architectural foundation but differs primarily in channel count. The DDS39RF10 specifically provides dual-channel outputs, whereas the RFS10 variant offers a single channel. Both utilize the same 16-bit DAC core and digital upconversion logic, allowing for flexible deployment in multi-carrier or MIMO architectures.

Replacement Considerations

The DDS39RFS10ACK serves as a functional alternative for designs requiring only a single output channel. Verify that the reduction from two channels to one does not impact the system's spatial processing or carrier aggregation requirements. Ensure that the pinout differences between the ACL and ACK suffixes do not necessitate PCB redesigns.
