AD9154BCPZ

Overview

The AD9154BCPZ is a quad, 16-bit high dynamic range digital-to-analog converter (DAC) from Analog Devices Inc. It supports a maximum sample rate of 2.4 GSPS and features an 8-lane JESD204B interface with Subclass 1 support for deterministic latency and multi-chip synchronization. The device integrates a low-noise PLL clock multiplier, digital inverse sinc filter, and numerically controlled oscillator (NCO). Key AC performance metrics at 180 MHz IF include an ACLR of 77 dBc for single-carrier LTE 20 MHz bandwidth, an IMD of 78 dBc for six-carrier GSM, and an SFDR of 72 dBc. Power consumption is 2.11 W at 1.6 GSPS.

Feature Summary

• Quad-channel 16-bit DAC architecture with 2.4 GSPS maximum update rate
• Flexible 8-lane JESD204B interface supporting up to 10.96 Gbps per lane
• Integrated low-noise PLL clock multiplier and digital datapath features
• Optimized for direct conversion transmit applications with complex modulation

Applications

• Multicarrier LTE and GSM base stations
• Software defined radios
• Point to point microwave radio
• Automated test equipment

Procurement Notes

Verify the specific suffix BC in the part number against the manufacturer's ordering guide to confirm temperature range and package variant. Ensure the design includes proper power supply decoupling and thermal management for the exposed pad LFCSP package to maintain specified electrical characteristics.

Selection Notes

Select this component when designing systems requiring high dynamic range and low spurious performance in the 100 MHz to 300 MHz frequency band. The integrated JESD204B interface reduces board congestion compared to parallel interfaces. Consider the 2.11 W power dissipation and ensure adequate heat sinking for the 88-lead LFCSP package.

Part Context

The AD9154 belongs to the TxDAC+ family of high-speed digital-to-analog converters. It is designed to interface seamlessly with RF quadrature modulators such as the ADRF6720-27. The device supports mix mode operation to reconstruct carriers in the second and third Nyquist zones, providing flexibility in system architecture.
