Fujitsu Microelectronics America said its new MB86065 is a 1.3GSps devicethe industry's fastest CMOS 14bit DAC.

"The MB86065 demonstrates the company's ability to support the trend toward commoditization in communications infrastructure equipment," said Stephanos Thomopoulos, senior product marketing manager. "The higher direct-IF frequencies impact end-applications significantly by reducing the overall design effort, thus lowering the total cost of ownership and speeding time-to-market."

The 1.3GSps DAC, a single-channel product derived from the company's MB86064 dual 14-bit, 1GSps DAC developed in 2003, guarantees direct-IF frequencies above 400MHz. This feature widens the spurious-free generating region and relaxes subsequent filtering requirements. The direct-IF architecture, more versatile than direct conversion, is designed to enable platform solutions capable of rapid re-targeting to different market and frequency plan requirements.

The MB86065 DAC is backward-compatible with the "DAC A" channel of the MB86064 and integrates the company's Waveform Memory Module, which allows waveforms to be downloaded and executed on-chip, thus cutting the need for a high-speed data generator.

The MB86065, housed in a EFBGA package measuring 12-by-12mm, will be priced at $34 each in 10,000-unit quantities. Customer development kits and sample devices will be available beginning in early 2007, with mass production scheduled for April.
