AD9912ABCPZ-REEL7

Overview

The AD9912ABCPZ-REEL7 is a direct digital synthesizer (DDS) featuring an integrated 14-bit digital-to-analog converter (DAC). It operates with a 1 GSPS internal clock speed and supports a 48-bit frequency tuning word for 4 μHz resolution. The device includes a differential HSTL comparator, a low noise PLL REFCLK multiplier, and two SpurKiller channels. It accepts flexible system clock inputs from crystals or external references. Power supplies are 1.8 V for analog/digital cores and 3.3 V for I/O. Operating temperature ranges from -40°C to +85°C in a 64-lead LFCSP package.

Feature Summary

• Integrated 14-bit DAC with 48-bit frequency tuning capability
• On-chip low noise PLL and SpurKiller harmonic reduction
• Differential HSTL and single-ended CMOS output drivers
• Flexible system clock input supporting crystal or external reference

Applications

• Agile LO frequency synthesis
• Low jitter, fine tune clock generation
• Test and measurement equipment
• Wireless base stations and controllers
• Secure communications

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure that the serial control interface parameters match the target system requirements. Check thermal resistance values if operating near maximum temperature limits. Confirm package integrity upon receipt.

Selection Notes

Select this component when high-resolution frequency synthesis is required with integrated DAC capabilities. Consider the 1 GSPS sampling rate and 48-bit tuning word for precise frequency steps. Evaluate the need for on-chip PLL multiplication versus external low-jitter clocks based on phase noise requirements. Verify power supply constraints for 1.8 V and 3.3 V domains.
