AD9161BBCZRL

Overview

The AD9161BBCZRL is a high-performance, single-channel, 11-bit RF digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It supports data rates up to 6 GSPS and achieves an effective update rate of up to 12 GSPS using its quad-switch architecture and 2× interpolator filter. The device features a JESD204B serial interface with up to eight lanes and an SPI for configuration. Key electrical parameters include a resolution of 11 bits, integral nonlinearity of ±2.7 LSB, and differential nonlinearity of ±1.7 LSB. It operates within a temperature range of -40°C to +85°C and utilizes analog supply voltages of 2.5 V and 1.2 V.

Feature Summary

• Quad-switch DAC core with 2× interpolation filter enabling up to 12 GSPS update rate.
• Up to eight JESD204B SERDES lanes for flexible data input.
• Mix-Mode operation supporting RF carrier reconstruction in Nyquist zones up to 7.5 GHz.
• Programmable full-scale output current ranging from 8 mA to 38.76 mA.

Applications

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

Procurement Notes

Verify the 'RL' suffix indicates tape-and-reel packaging when sourcing. Confirm that the specific revision matches the required datasheet version, as performance specifications may vary between revisions. Ensure compatibility with the 169-ball CSP_BGA package dimensions for PCB layout.

Selection Notes

Select this component for applications requiring high dynamic range and direct RF synthesis up to 7.5 GHz. Compare against the AD9162 if 16-bit resolution is required instead of 11 bits. Consider power dissipation limits at clock speeds exceeding 5.1 GSPS, which require junction temperatures below 105°C.

Part Context

This part belongs to the AD9161/AD9162 family of RF DACs designed for demanding high-speed signal processing. It shares architectural similarities with other members like the AD9163 and AD9164 but is distinct in its 11-bit resolution and single-channel configuration optimized for specific bandwidth and power constraints.

Replacement Considerations

The AD9162 offers identical functionality with 16-bit resolution. The AD9163 provides 16-bit resolution with potentially different performance characteristics. Verify pinout and software register compatibility before substituting.
