CMOS DAC Provides Superior Sampling Rates and Spectral Performance

Fujitsu Microelectronics, Inc. (FMI) today introduced the MB86061, a digital-to-analog converter (DAC) that provides high-speed, high-resolution conversion capabilities for communications base stations, advanced antenna systems, test equipment, satellite uplinks and ultra-high-resolution imaging systems.

Fujitsu's MB86061 CMOS DAC provides a 12-bit 400MSa/s sampling rate with emitter coupled logic (ECL) compatible I/Os, which means it delivers overall system performance typical of Bipolar/BiCMOS devices. The MB86061, which is fabricated in an advanced 0.35 micron CMOS Triple Well process, outperforms traditional bipolar/BiCMOS ECL digital-to-analog converters in most applications. Superior spectral performance is achieved via the device's proprietary segment shuffling, which improves large-signal linearity of the converter's transfer function, where spurious energy is redistributed as noise.

"Our customers can rely on our new DAC to perform very well under the stress of system conditions in communications, test and imaging systems," said Keith Horn, marketing director of FMI's System Solutions Group. "This new device is the latest in a family that is becoming very popular in advanced applications." Fujitsu introduced its first DAC, the MB86060, last year.

The MB86061 also offers board-area savings of up to 68 percent when compared with equivalent devices. Because it is fabricated in CMOS, the new DAC offers a saving in power consumption of up to 72 percent when measured against bipolar/BiCMOS solutions.

This power reduction enables further system savings in support circuits, such as the power supply. In addition, no heat sinks are required for external thermal management, because the DAC can operate within the power dissipation capability of the 64-pin Quad Flat Pack (QFP) package.

A customer development kit, DK86061-3, is available, which allows designers to evaluate the device and verify performance under specific conditions before committing to prototype development.

The MB86061 is now in production, packaged in the 64-pin QFP. Pricing begins at $48 each in 1,000-piece quantities.
