DAC38RF83GIAAV

Digital To Analog Converters Overview

The DAC38RF83GIAAV is a dual-channel, 14-bit, 9-GSPS RF-sampling digital-to-analog converter (DAC) manufactured by Texas Instruments. It features an on-chip phase-locked loop (PLL) and supports 6x to 24x interpolation. The device operates within a temperature range of -40°C to 85°C and utilizes a JESD204B interface for data input. Packaged in a 144-ball FCBGA format measuring 10 mm x 10 mm, it provides single-ended or differential output options with analog supply voltages of 1 V and 1.8 V, and a digital supply voltage of 1 V.

Digital To Analog Converters Feature Summary

• Integrates a high-performance on-chip PLL and voltage-controlled oscillator (VCO) for direct RF synthesis capabilities.
• Supports flexible multi-mode operation including 14-bit dual-channel, 16-bit dual-channel, and 8-bit single-channel configurations.
• Features a low-power JESD204B interface supporting Sub-class 1 for precise multi-device synchronization.

Digital To Analog Converters Applications

• Direct RF synthesis for DOCSIS 3.0/3.1 cable modem termination systems
• Radar and electronic warfare signal generation
• Microwave backhaul communication links

Digital To Analog Converters Part Context

This component belongs to the DAC38RF83 family of ultra-high-speed RF sampling DACs from Texas Instruments. It shares architectural similarities with variants such as the DAC38RF82, DAC38RF87, and DAC38RF90, differing primarily in specific interpolation factors and PLL frequency ranges while maintaining the same 14-bit resolution and 9-GSPS sample rate core.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitute part numbers for the DAC38RF83GIAAV are not available in the provided documentation. Designers should verify pinout and electrical compatibility with other members of the DAC38RFxx family before substitution.
