AD9154BCPAZ

Overview

The AD9154BCPAZ is a quad, 16-bit, high dynamic range digital-to-analog converter (DAC) from Analog Devices Inc. It provides a maximum sample rate of 2.4 GSPS and supports input data rates up to 1.096 GSPS via an 8-lane JESD204B interface. The device features a flexible architecture with selectable 1×, 2×, 4×, and 8× interpolation filters, a digital inverse sinc filter, and a numerically controlled oscillator (NCO). Key performance metrics at 180 MHz IF include an ACLR of 77 dBc for single-carrier LTE, 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.

• Integrated low-noise PLL clock multiplier and digital datapath including NCO and inverse sinc filter
• Programmable full-scale output current ranging from 4 mA to 20 mA

Applications

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

Procurement Notes

Verify the specific suffix 'CPAZ' against the manufacturer's ordering guide to confirm package type and temperature grade. Ensure that the required supply voltages (AVDD33, DVDD12, SVDD12, etc.) are correctly generated on the PCB. Confirm that the board layout accommodates the 88-lead LFCSP exposed pad thermal requirements.

Selection Notes

Select this component when designing systems requiring high dynamic range and wide bandwidth in a compact form factor. The integrated JESD204B interface simplifies FPGA connections. Consider the power consumption of 2.11 W at 1.6 GSPS for thermal management. Verify compatibility with external RF quadrature modulators like the ADRF6720-27 if direct conversion architectures are used.

Part Context

The AD9154 belongs to the TxDAC+ family of high-speed DACs. It is designed for complex transmit applications where deterministic latency and multi-chip synchronization are critical. The device integrates features such as gain, phase, and offset compensation, making it suitable for MIMO and transmit diversity systems without requiring extensive external correction circuitry.
