AD9164BBCZ

Overview

The AD9164BBCZ is a high-performance 16-bit digital-to-analog converter (DAC) and direct digital synthesizer (DDS) from Analog Devices. It supports DAC update rates up to 6 GSPS, reaching 12 GSPS with the 2× interpolator enabled. The device features a quad-switch architecture and integrates 32 numerically controlled oscillators (NCOs). Key specifications include ±2.7 LSB integral nonlinearity (INL), ±1.7 LSB differential nonlinearity (DNL), and a full-scale output current range of 8 mA to 38.76 mA. It utilizes an eight-lane JESD204B interface and operates within an ambient temperature range of -40°C to +85°C.

Feature Summary

• DAC update rate up to 12 GSPS with 2× interpolation enabled
• Integrated DDS with 32, 32-bit NCOs for phase-coherent fast frequency hopping
• Eight-lane JESD204B SERDES interface supporting lane rates up to 12.5 Gbps
• Mix-Mode operation enabling RF carrier reconstruction 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 suffix BBCZ indicates the leaded ball option in the 169-ball, 11 mm × 11 mm, 0.8 mm pitch CSP_BGA package. Confirm power supply filtering requirements for VDD12_CLK and VDD12A pins to ensure lowest noise performance. Ensure thermal management measures are adequate as the device can dissipate nearly 3 W depending on configuration.

Selection Notes

Select this component for demanding high-speed RF applications requiring wide analog bandwidth and high dynamic range. The AD9164BBCZ is suitable for baseband modes up to 2.5 GHz and 2× NRZ modes up to 6 GHz. Consider the Mix-Mode capability if signal synthesis in the second or third Nyquist zones up to 7.5 GHz is required.

Part Context

The AD9164 belongs to the AD9164 series of 16-bit RF DACs. The BBCZ variant specifically denotes the leaded ball option within the 169-pin CSP_BGA package family. This distinguishes it from the BBCAZ variant, which uses a different package pitch and has distinct SYSREF± timing specifications.
