AD9135BCPAZ

Overview

The AD9135BCPAZ is a dual-channel, 11-bit digital-to-analog converter (DAC) from Analog Devices. It supports a maximum sample rate of 2800 MSPS and features an 8-lane JESD204B interface. Key specifications include a spurious-free dynamic range (SFDR) of 82 dBc at DC IF with −9 dBFS input, and a typical power consumption of 1.42 W at 1600 MSPS. The device integrates a programmable transmit enable function, selectable interpolation filters (1× to 8×), and a high-performance PLL clock multiplier. It is housed in an 88-lead LFCSP package.

Feature Summary

• Dual-channel architecture with 11-bit resolution and 2800 MSPS maximum update rate
• Flexible 8-lane JESD204B serial interface supporting Subclass 1 for deterministic latency
• Proprietary low spurious design achieving 82 dBc SFDR at DC IF
• Integrated high-performance PLL clock multiplier and digital inverse sinc filter

Applications

• Wireless communications including 3G/4G W-CDMA base stations
• Software defined radios and wideband repeaters
• Point-to-point and local multipoint distribution service (LMDS)
• Automated test equipment and instrumentation

Procurement Notes

Verify the specific suffix 'BCPAZ' against the manufacturer's current ordering guide to confirm package type and environmental compliance. Ensure that the required supply voltages (AVDD33, PVDD12, DVDD12, etc.) match the system design constraints before procurement.

Selection Notes

Select this component for applications requiring high dynamic range and ultrawide complex signal bandwidth exceeding 2 GHz. Consider the AD9136 variant if 16-bit resolution is required instead of 11-bit. Verify that the host FPGA or processor can support the necessary JESD204B lane rates up to 12.4 Gbps per lane.

Part Context

This part belongs to the AD9135/AD9136 family of TxDAC+® digital-to-analog converters. These devices are designed for high-speed signal processing and are optimized for seamless interfacing with Analog Devices analog quadrature modulators such as the ADRF6720.

Replacement Considerations

The AD9136BCPAZ is the primary alternative within the same datasheet, offering identical performance characteristics but with 16-bit resolution instead of 11-bit.
