AD9136BCPAZ

Overview

The AD9136BCPAZ is a dual-channel, 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., operating at a maximum sample rate of 2.8 GSPS. It features an 8-lane JESD204B interface and supports Subclass 1 for deterministic latency. Key specifications include a typical SFDR of 82 dBc at DC IF with -9 dBFS input, and a power consumption of 1.42 W at 1.6 GSPS. The device integrates a high-performance PLL clock multiplier, selectable interpolation filters (1× to 8×), and a digital inverse sinc filter. It is housed in an 88-lead LFCSP package with an exposed pad.

Feature Summary

• Dual 16-bit DACs with 2.8 GSPS maximum update rate
• Flexible 8-lane JESD204B interface supporting Subclass 1
• High dynamic range performance: 82 dBc SFDR at DC IF
• Integrated high-performance PLL and digital inverse sinc filter

Applications

• Wireless communications base stations
• Software defined radios
• Wideband repeaters
• Point-to-point microwave links

Procurement Notes

Verify the specific suffix 'BCPAZ' against the manufacturer's ordering guide to confirm the exact temperature grade and packaging configuration. Ensure that the required supply voltages (AVDD33, PVDD12, SVDD12, etc.) are correctly generated on the PCB layout. Confirm that the design supports the necessary thermal dissipation for the 88-lead LFCSP package under full operating conditions.

Selection Notes

Select the AD9136BCPAZ when a dual-channel solution with 16-bit resolution and high bandwidth is required. Compare it with the AD9135 if lower resolution or cost is a priority. Ensure the system design accommodates the 8-lane JESD204B interface requirements and the specific voltage levels for the SERDES and analog supplies as detailed in the electrical specifications.

Part Context

The AD9136 is part of the TxDAC+ family, designed for high-speed data conversion applications. It shares the same package and many functional blocks with the AD9135, differing primarily in resolution. Evaluation boards such as the AD9136-EBZ and AD9136-FMC-EBZ are available for development and testing purposes.

Replacement Considerations

The AD9135 is a compatible alternative within the same family offering 11-bit resolution. Verify pin compatibility and software register settings when substituting between models. No other direct cross-model replacements are documented in the provided datasheet.
