AD9119BBCZRL

Overview

The AD9119BBCZRL is an 11-bit RF digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It supports a DAC update rate of up to 5.7 GSPS, enabling direct RF synthesis at data rates up to 2.85 GSPS. The device utilizes a quad-switch architecture with dual-edge clocking to achieve high dynamic range and bandwidth for multicarrier generation up to 4.2 GHz. Key electrical parameters include a full-scale output current range of 9.1 mA to 34.9 mA, operating from +1.8 V analog/digital supplies and −1.5 V analog supply. It features dual-port LVDS or DHSTL interfaces, source synchronous DDR clocking, and on-chip interpolation filters.

Feature Summary

• Quad-switch architecture enables dual-edge clocking for DAC update rates up to 5.7 GSPS.
• Supports DC to 1.425 GHz in baseband mode and 1.425 GHz to 4.2 GHz in Mix-Mode operation.
• Dual-port LVDS and DHSTL data interfaces with source synchronous DDR clocking support up to 1.425 GSPS input rates.
• Integrated 2× interpolation filter and internal voltage reference.

Applications

• Broadband communications systems
• CMTS/VOD infrastructure
• Wireless infrastructure including W-CDMA and LTE
• Radar and jamming systems

Procurement Notes

Verify the specific suffix 'BBCZRL' against the manufacturer's ordering guide to confirm package type, temperature range, and reel quantity specifications. Ensure compatibility with the required 160-ball CSP-BGA footprint and thermal management requirements during procurement planning.

Selection Notes

Select this component for applications requiring high-speed RF synthesis with 11-bit resolution. Consider the Mix-Mode capability for signals between 1.425 GHz and 4.2 GHz. Verify that the host system can provide the necessary dual-port LVDS/DHSTL interface and that power dissipation constraints are met within the -40°C to +85°C operating range.

Part Context

The AD9119 is part of the AD9119/AD9129 family of high-performance RF DACs. While the AD9129 offers 14-bit resolution, the AD9119 provides 11-bit resolution with identical update rates and architectural features. Both devices share the same pinout and operational modes, differing primarily in bit depth and associated linearity specifications.

Replacement Considerations

The AD9129BBCZRL is a compatible alternative within the same family offering 14-bit resolution. Other members of the AD91xx series may offer different resolutions or update rates but require verification of pin compatibility and performance metrics.
