AD9162BBCAZRL

Overview

The AD9162BBCAZRL is a 16-bit single-channel RF digital-to-analog converter (DAC) from Analog Devices. It supports data rates up to 6 GSPS with an effective update rate of up to 12 GSPS using its quad-switch architecture and 2× interpolator filter. The device operates on analog supply voltages of 1.2 V and 2.5 V, and digital supplies of 1.2 V and 2.5 V. It features a JESD204B interface with up to eight lanes and an SPI for configuration. The component is housed in a 169-ball, 11 mm × 11 mm, 0.8 mm pitch CSP_BGA package.

Feature Summary

• 16-bit resolution with DAC update rates up to 12 GSPS minimum.
• Supports direct RF synthesis at 6 GSPS and Mix-Mode operation up to 7.5 GHz.
• Configurable output current ranging from 8 mA to 38.76 mA.
• Up to eight JESD204B SERDES lanes with programmable lane speed.

Applications

• Broadband communications systems
• DOCSIS 3.1 cable modem termination system (CMTS)
• Wireless communications infrastructure (W-CDMA, LTE, LTE-A)
• Radar and jammer systems

Procurement Notes

Verify the specific suffix AZRL against the manufacturer's ordering guide to confirm the leaded ball option and reel packaging details. Ensure compatibility with the 169-ball CSP_BGA footprint during procurement planning. Cross-reference the revision history for any recent updates to electrical specifications or thermal management requirements before finalizing orders.

Selection Notes

Select this component for applications requiring high dynamic range and signal reconstruction bandwidth up to 7.5 GHz. The AD9162 is suitable for DOCSIS 3.1 compliance due to its wide bandwidth and dynamic range margins. Consider the power dissipation characteristics, which vary significantly based on interpolation factors and NCO usage, when designing the thermal solution.

Part Context

The AD9162 belongs to the AD9161/AD9162 family of high-performance RF DACs. While the AD9161 offers 11-bit resolution, the AD9162 provides 16-bit resolution, catering to more demanding linearity requirements. Both share the same core architecture, supporting similar data rates and interface options, but differ in bit depth and specific performance metrics like SFDR.

Replacement Considerations

The AD9161BBCAZRL is a pin-compatible alternative within the same family, offering 11-bit resolution instead of 16-bit. Designers requiring lower resolution but potentially different cost or power profiles may consider this substitute. Verify that the application does not strictly require the 16-bit precision provided by the AD9162.

FAQ
