AD9958BCPZ-REEL7

Overview

The AD9958BCPZ-REEL7 is a dual-channel Direct Digital Synthesis (DDS) integrated circuit manufactured by Analog Devices Inc. It features two synchronized DDS cores operating at a maximum sample rate of 500 MSPS, each equipped with a 10-bit digital-to-analog converter (DAC). The device supports independent frequency, phase, and amplitude control for each channel, utilizing a 32-bit frequency tuning word, 14-bit phase offset, and 10-bit output scale multiplier. It operates on dual supplies: 1.8 V for the DDS core and 3.3 V for the serial I/O interface. Key specifications include a frequency tuning resolution of 0.12 Hz or better, channel-to-channel isolation exceeding 72 dB, and an SPI-compatible serial port with up to 800 Mbps throughput.

Feature Summary

• Dual synchronized DDS channels with independent frequency, phase, and amplitude control capabilities
• Integrated linear frequency, phase, and amplitude sweeping functionality
• Supports up to 16 levels of modulation via pin-selectable profile inputs
• Includes a programmable reference clock multiplier ranging from 4× to 20×

Applications

• Agile local oscillators
• Phased array radars and sonars
• RF source for Acousto-Optic Tunable Filters (AOTF)
• Quadrature communications systems

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel configuration. Ensure compatibility with the required voltage levels, specifically the 1.8 V core supply and 3.3 V I/O supply. Confirm that the component meets the necessary industrial temperature range requirements for the intended deployment environment.

Selection Notes

Select this component when dual-channel synchronization and high-speed direct digital synthesis are required. Consider the 500 MSPS maximum sample rate and 10-bit DAC resolution for signal generation needs. Evaluate the need for internal PLL multiplication if the available reference clock frequency is lower than the desired system clock rate.

Part Context

This part belongs to the AD9958 series of dual-channel DDS devices. It shares functional similarities with other members of the family but is distinguished by its specific package configuration and reel packaging format indicated by the suffix. It serves as a high-performance solution for applications requiring precise multi-channel waveform generation.

Replacement Considerations

Consult official substitution guides for verified alternatives. Cross-reference pinouts and electrical specifications carefully before replacing components in existing designs.
