AD9164BBCAZRL

Overview

The AD9164BBCAZRL is a high-performance, single-channel 16-bit digital-to-analog converter (DAC) and direct digital synthesizer (DDS). It supports update rates up to 6 GSPS directly, with an effective rate of up to 12 GSPS when utilizing the internal 2× interpolator filter. The device features a quad-switch DAC core and integrates 32 numerically controlled oscillators for phase-coherent fast frequency hopping via a 100 MHz SPI interface. Data input is handled by up to eight JESD204B SERDES lanes. It operates within an ambient temperature range of -40°C to +85°C and is housed in a 165-ball, 8 mm × 8 mm, 0.5 mm pitch CSP_BGA package.

Feature Summary

• 16-bit resolution with DAC update rates up to 6 GSPS (direct) and 12 GSPS (with 2× interpolation enabled).
• Integrated DDS with 32, 32-bit NCOs supporting phase-coherent fast frequency hopping.
• Up to eight programmable JESD204B SERDES lanes for flexible data interface configuration.
• Mix-Mode operation enables RF carrier reconstruction in the second and third Nyquist zones up to 7.5 GHz.

Applications

• Broadband communications systems
• DOCSIS 3.1 CMTS, video on demand (VOD), and edge quadrature amplitude modulation (EQAM)
• Wireless communications infrastructure including W-CDMA, LTE, and LTE-A

Procurement Notes

Verify the specific suffix 'BBCA' corresponds to the 165-ball, 8 mm × 8 mm, 0.5 mm pitch CSP_BGA package variant. Confirm that the ordering code matches the required leaded ball option if applicable, as package dimensions and pin counts vary across the AD9164 family. Ensure compatibility with the specified operating temperature range of -40°C to +85°C.

Selection Notes

Select this component for applications requiring high dynamic range and signal reconstruction bandwidth up to 7.5 GHz. The AD9164 is suitable for DOCSIS 3.1 compliance and multiband wireless standards. Consider the power dissipation profile, which can approach 3 W depending on the configuration, and ensure adequate thermal management via the exposed die package is implemented on the PCB.

Part Context

The AD9164 belongs to Analog Devices' high-speed RF DAC portfolio designed for demanding signal synthesis applications. It distinguishes itself through the combination of a 16-bit DAC core with a built-in DDS engine, allowing for complex waveform generation and rapid frequency agility without external processing overhead.

FAQ

What is the maximum output current range for the AD9164?

The output current can be programmed from 8 mA to 38.76 mA.

How does the AD9164 achieve an update rate of 12 GSPS?

It achieves this effective rate by coupling the quad-switch DAC core with a 2× interpolator filter (FIR85), effectively doubling the base update rate in supported modes.

What is the purpose of the Mix-Mode operation?

Mix-Mode allows the AD9164 to reconstruct RF carriers in the second and third Nyquist zones, supporting frequencies up to 7.5 GHz while maintaining exceptional dynamic range.
