Fujitsu Microelectronics Europe (FME) has introduced the MB86064 dual 14-bit, 800MSa/s DAC, which the company hopes to be instrumental in enabling new architectures to reduce the costs of existing cellular infrastructures, while simultaneously addressing future needs.

Implemented using the company's advanced mixed signal CS80A 0.18?m CMOS process, the device is the first Application Specific Standard Product (ASSP) based on its Next Generation DAC technology.

"This ASSP is integral to the roll-out of our latest DAC technology, opening up more opportunities and markets. The price/performance point achieved enables the cost-effective realization of high direct-IF multi-carrier systems for GSM, W-CDMA and UMTS," said Neil Amos, Director of FME's Mixed Signal Division.

The product features an enhanced current switch and switch driver design to provide constant data-independent switching delay, reduce jitter, and distortion. It also has on-chip vector memories to enable waveforms to be downloaded and executed on-chip.

A segment shuffling function is also included to improve performance in next generation systems and high direct-IF architectures by moving distortion products out-of-band and reducing device-to-device variation. Other features in the dual DAC core include LVDS data inputs and a serial control port.

The MB86064 is housed in Fujitsu's 120-ball EFBGA package measuring 12-by-12mm.
