Overview
The AD9135BCPZ 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 typical spurious-free dynamic range (SFDR) of 82 dBc at DC IF with -9 dBFS input, and a settling time of 20 ns. The device operates within a temperature range of -40°C to +85°C and consumes approximately 1.74 W at 1.6 GSPS. It utilizes a proprietary low spurious design and includes programmable interpolation filters.
Feature Summary
- Dual-channel architecture with 11-bit resolution and 2.8 GSPS maximum update rate
- Flexible 8-lane JESD204B serial interface supporting Subclass 1 for synchronization
- Proprietary low spurious and distortion design achieving 82 dBc SFDR at DC IF
- Integrated high-performance PLL clock multiplier and selectable interpolation filters
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)
- Transmit diversity and multiple input/multiple output (MIMO) systems
- Automated test equipment and instrumentation
Procurement Notes
Verify the specific suffix 'BCPZ' against the manufacturer's current ordering guide to confirm package type and temperature grade. Ensure compatibility with required supply voltages (AVDD33, DVDD12, SVDD12) and check for moisture sensitivity handling requirements during storage and assembly.
Selection Notes
Select this component for applications requiring ultrawide complex signal bandwidth greater than 2 GHz. Consider the 88-lead LFCSP package constraints and thermal resistance characteristics. Verify that the host system can support the JESD204B lane rates up to 12.4 Gbps per lane if operating at maximum speeds.
Part Context
This part belongs to the AD9135/AD9136 family of TxDAC+ Digital-to-Analog Converters. The AD9135 variant specifically provides 11-bit resolution, whereas the AD9136 offers 16-bit resolution. Both share the same functional block diagram and interface capabilities but differ in accuracy and linearity specifications.
Replacement Considerations
The AD9136BCPZ is a direct pin-compatible alternative within the same datasheet offering higher 16-bit resolution. Other series members like the AD9144 provide different performance profiles and should be evaluated based on specific speed and resolution requirements.
