AD9136BCPAZRL

Overview

The AD9136BCPAZRL is a dual, 16-bit digital-to-analog converter (DAC) from Analog Devices Inc., part of the TxDAC+ family. It supports a maximum sample rate of 2800 MSPS and features an 8-lane JESD204B interface with lane rates up to 12.4 Gbps. Key electrical parameters include a spurious-free dynamic range (SFDR) of 82 dBc at DC IF with -9 dBFS input, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±2 LSB. The device operates on analog supplies of 3.3 V and digital supplies of 1.2 V or 1.3 V, consuming approximately 1.74 W at 1.6 GSPS. It is housed in an 88-lead LFCSP package.

Feature Summary

• Dual-channel architecture with 16-bit resolution and 2.8 GSPS maximum update rate.
• Flexible 8-lane JESD204B serial interface supporting Subclass 1 for deterministic latency.
• Programmable interpolation filters (1×, 2×, 4×, 8×) and digital inverse sinc filter.
• Integrated high-performance PLL clock multiplier and transmit enable function for power management.

Applications

• Wireless communications base stations (3G/4G W-CDMA).
• Wideband repeaters and software-defined radios.
• Point-to-point microwave radio systems.
• Local multipoint distribution service (LMDS) and multichannel multipoint distribution service (MMDS).

Procurement Notes

Verify the 'RL' suffix indicates reel packaging when sourcing. Confirm supply voltage requirements (1.2 V vs 1.3 V digital) match system design, as this affects maximum DAC update rates. Ensure thermal management meets the exposed pad soldering requirements for the 88-lead LFCSP package.

Selection Notes

Select the AD9136BCPAZRL over the AD9135 if 16-bit resolution is required for higher dynamic range applications. Verify that the host FPGA can support the necessary JESD204B lane count and data rates. Consider the fixed latency characteristics and interpolation filter settings when designing the digital datapath timing.

Part Context

This component belongs to the AD9135/AD9136 family of high-speed DACs designed for wideband signal synthesis. It shares functional similarities with the AD9135 but offers increased resolution. The BC grade denotes specific performance binning within the product line.

Replacement Considerations

The AD9135BCPZRL is a compatible alternative if 11-bit resolution is sufficient. For higher speed requirements, consider the AD9177 series. Verify pinout compatibility and register configuration differences before substitution.
