Overview
The Texas Instruments DDS39RFS12ACK is a single-channel, 16-bit Direct Digital Synthesizer (DDS) featuring a multi-Nyquist DAC core. It supports a maximum clock frequency of 12 GHz and operates within a supply voltage range of 1.71 V to 1.89 V. The device utilizes an FCBGA-256 package and includes four converters with one dedicated DAC channel. Key performance metrics include a differential nonlinearity (DNL) of 2.2 LSB and integral nonlinearity (INL) of 9 LSB. It features an SPI interface for control and operates between -40°C and +85°C.
Feature Summary
- Integrates a 16-bit multi-Nyquist DAC kernel capable of direct RF sampling or complex baseband signal generation.
- Supports arbitrary waveform generation (AWG) and direct digital synthesis (DDS) with phase-coherent frequency hopping.
- Includes a 64-bit Numerically Controlled Oscillator (NCO) for high-resolution frequency tuning.
Applications
- Satellite communication (SATCOM) systems
- Phased array antenna beamforming
- Synthetic Aperture Radar (SAR) exciters
Procurement Notes
Verify the specific suffix 'ACK' against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure compatibility with JESD204B/C interfaces if used in high-speed data acquisition chains. Confirm humidity sensitivity handling requirements during storage and assembly processes.
Selection Notes
Select this model when a single-channel output is required for direct RF sampling applications up to 12 GHz. Compare against the dual-channel DDS39RF12ACK variant if multiple independent signal paths are needed. Verify that the 16-bit resolution meets the dynamic range requirements for the intended carrier frequencies.
Part Context
This component belongs to the DDS39RF12 series of specialized data acquisition devices. It shares architectural similarities with the DDS39RF10 series but offers higher sampling rates and bandwidth capabilities. The series is designed for high-performance signal generation in demanding RF environments.
Replacement Considerations
The DDS39RF12ACK serves as the single-channel counterpart to the dual-channel DDS39RF12ACK. No other direct pin-compatible substitutes are documented in the provided reference material.
