AD9993BBCZ

Overview

The AD9993BBCZ is a mixed-signal front-end integrating four 14-bit ADCs and two 14-bit DACs. The ADCs operate at 250 MSPS with an SFDR of 83 dBc at 87 MHz input. The DACs run at 500 MSPS, achieving an SFDR of 75 dBc at 20 MHz output. It features an on-chip PLL clock synthesizer supporting master clocks up to 1 GHz. Power consumption is 1536 mW at 1 GHz. Interfaces include LVDS for data and SPI for control. The device is housed in a 12 mm × 12 mm lead-free BGA package.

Feature Summary

• Integrates four 14-bit ADCs and two 14-bit DACs in a single chip
• Includes an on-chip PLL clock synthesizer for flexible clocking
• Supports high-speed LVDS interfaces for both ADC outputs and DAC inputs
• Contains FIFO buffers to manage phase differences between clocks

Applications

• Point-to-point microwave backhaul radios
• Wireless repeaters

Procurement Notes

Verify the specific suffix BBCZ corresponds to the required temperature grade and packaging variant. Confirm that the ordering information matches the current Analog Devices datasheet revision. Ensure compatibility with system voltage requirements before procurement.

Selection Notes

Select this component when a compact solution combining multiple high-speed converters is needed. Consider the integrated PLL if external clock generation is undesirable. Evaluate power consumption against thermal constraints given the 1536 mW typical dissipation. Verify interface compatibility with the host processor's SPI controller.

Part Context

This part belongs to the Analog Devices MxFE family, designed to simplify transceiver designs by consolidating analog and digital functions. It targets applications requiring high channel counts and precise timing synchronization within a small footprint.

Replacement Considerations

Check for updated revisions or pin-compatible alternatives within the MxFE portfolio. Verify that any substitute maintains the same resolution, sampling rates, and package dimensions.
