AD9164BBCAZ

Overview

The AD9164BBCAZ is a high-performance 16-bit digital-to-analog converter (DAC) and direct digital synthesizer (DDS) from Analog Devices. It supports update rates up to 6 GSPS, reaching 12 GSPS with the 2× interpolator filter enabled. The device features a quad-switch DAC core, 32 numerically controlled oscillators (NCOs), and an SPI interface for configuration. It utilizes up to eight JESD204B SERDES lanes for data input. Key specifications include ±2.7 LSB integral nonlinearity (INL), ±1.7 LSB differential nonlinearity (DNL), and programmable output current from 8 mA to 38.76 mA. Operating temperatures range from -40°C to +85°C.

Feature Summary

• DAC update rate up to 12 GSPS in 2× NRZ mode
• Direct RF synthesis up to 6 GHz in baseband/NRZ modes
• Mix-Mode operation supporting RF carriers up to 7.5 GHz
• Integrated DDS with 32 NCOs for phase-coherent fast frequency hopping

Applications

• Broadband communications systems
• DOCSIS 3.1 CMTS/VOD/EQAM infrastructure
• Wireless communications infrastructure (W-CDMA, LTE, LTE-A)
• Point-to-point wireless links

Procurement Notes

Verify the specific suffix BBCAZ corresponds to the 169-ball, 11 mm × 11 mm, 0.8 mm pitch CSP_BGA package with leaded ball options as documented in the datasheet. Confirm that the ordering code matches the required pinout and thermal characteristics for the target PCB design.

Selection Notes

Select this component for applications requiring high dynamic range and signal reconstruction bandwidth up to 7.5 GHz. Ensure the system design accommodates the power dissipation of approximately 2.65 W by implementing adequate thermal management via the exposed die. Verify compatibility with JESD204B interfaces and SPI control requirements.

Part Context

The AD9164 belongs to the AD9164 series of RF DACs designed for demanding high-speed radio frequency applications. It serves as a successor to previous generation converters, offering improved performance metrics such as higher update rates and integrated digital signal processing capabilities like interpolation filters and NCOs within a single chip.
