AD9913BCPZ

Overview

The AD9913BCPZ is a low-power direct digital synthesizer (DDS) featuring an integrated 10-bit DAC. It operates on a single 1.8 V supply and supports sampling rates up to 250 MSPS, generating analog output frequencies up to 100 MHz. Key electrical specifications include a power consumption of 50 mW at maximum internal clock speed, frequency resolution of 0.058 Hz, and phase tuning resolution of 0.022°. The device offers a spurious-free dynamic range (SFDR) of 80 dB at 100 MHz with ±100 kHz offset and phase noise ≤ –135 dBc/Hz at a 1 kHz offset. It functions within an extended industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrated 10-bit DAC with high-speed operation up to 250 MSPS for complete DDS functionality.
• Advanced power management allowing individual block shutdown and software/hardware controlled power-down modes.
• Flexible clocking architecture supporting crystal-driven oscillators, CMOS inputs, and optional PLL multipliers.
• Programmable linear sweep capability and support for eight frequency or phase offset profiles.

Applications

• Portable and handheld equipment requiring strict power limits
• Agile local oscillator (LO) frequency synthesis
• Programmable clock generators
• FM chirp sources for radar and scanning systems

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 32-lead LFCSP package variant when sourcing. Confirm that the ordering code matches the Rev E datasheet specifications. Ensure compatibility with the required 1.8 V supply rails for AVDD, DVDD, and DVDD_I/O. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component for applications demanding low power consumption alongside high-frequency agility. The AD9913 is suitable where programmable modulus mode is needed for non-power-of-two frequency ratios. Consider the 32-lead LFCSP package constraints for PCB layout. Evaluate the need for internal PLL multiplication versus external clock driving based on system jitter requirements.

Part Context

The AD9913 belongs to Analog Devices' family of low-power direct digital synthesizers. It succeeds earlier DDS solutions by significantly reducing power dissipation while maintaining high performance. The BC prefix typically denotes the industrial temperature grade and specific packaging configuration within the broader AD9913 product line.

Replacement Considerations

Direct substitutes may include other ADI DDS devices like the AD9850, though power and performance characteristics differ significantly. Verify pinout compatibility if replacing in existing designs. Cross-reference with AD9911 or AD9914 for higher performance or different interface needs, noting that these are not pin-compatible replacements.
