AD9164BBCA

Overview

The AD9164BBCA 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, with an effective rate of 12 GSPS enabled by a quad-switch architecture and 2× interpolator filter. The device features excellent dynamic range and bandwidth for demanding RF applications. Key specifications include a resolution of 16 bits, current output programmable from 8 mA to 38.76 mA, and analog supply voltages of 1.2 V and 2.5 V. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• DAC update rate up to 12 GSPS (minimum) in specific modes
• Direct RF synthesis at 6 GSPS (minimum)
• Up to eight JESD204B SERDES lanes with programmable speed
• Integrated DDS with 32 numerically controlled oscillators (NCOs)

Applications

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

Procurement Notes

Verify the suffix 'CA' against official documentation to confirm lead-free status and package variant. Confirm availability through authorized distributors as stock levels fluctuate. Ensure compliance with RoHS directives if required for the specific application environment.

Selection Notes

Select this component for applications requiring high-speed RF signal generation up to 7.5 GHz in Mix-Mode. Consider the 165-ball CSP_BGA package dimensions (8 mm × 8 mm) for PCB layout constraints. Evaluate power dissipation requirements, as the device can dissipate nearly 3 W depending on configuration.

Part Context

The AD9164 belongs to the AD9164 series of RF DACs designed for software-defined radio and high-speed data conversion. It integrates interpolation filters and NCOs to simplify system design. The BBCA suffix denotes a specific package and material composition variant within the broader AD9164 product line.

Replacement Considerations

Check for AD9164 variants with different suffixes for package or environmental differences. Cross-reference with AD9162 or AD9163 if lower performance or different pin counts are acceptable, though these are distinct part numbers.

FAQ

What is the maximum DAC update rate?

The AD9164 supports a minimum DAC update rate of 6 GSPS directly, which can reach up to 12 GSPS when using the 2× interpolator filter in certain modes.

How many JESD204B lanes does the AD9164 support?

The AD9164 data interface consists of up to eight JESD204B serializer/deserializer (SERDES) lanes, which are programmable in terms of lane speed and number.

What is the operating temperature range?

The AD9164 operates within a temperature range of -40°C to +85°C.
