CMOS 14bit DAC from Crest Technologies

Supplier News

Fujitsu’s new MB86065 distributed by Crest Technologies is a 1.3 GSps device that is a fast 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 1.3 GSps DAC, a single-channel product derived from Fujitsu’s '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 Fujitsu'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 is housed in a EFBGA package measuring 12-by-12 mm.
