MB86064 High Speed DAC (Digital to Analog Converter)

The Fujitsu MB86064 is a Dual 14-bit 1GSa/s digital to analog converter (DAC), delivering exceptional dynamic performance. Each high performance DAC core is capable of generating multi-carrier, multi-standard communication transmit signals, suitable for 2, 2.5 and 3G systems. DAC data is input via two high-speed LVDS ports. These operate in a pseudo double data rate (DDR) mode, with data latched on both rising and falling edges. Alternatively, the device can be configured as a multiplexed dual port single DAC. To simplify system integration the DAC operates from a clock running at half the DAC conversion rate. Analog performance at high frequencies is enhanced by novel current switch and switch driver designs which provide constant data-independent switching delay, reducing jitter and distortion.

[…] Afted the sucessful of MB86064 High Speed DAC (1GSa/s ), the winner of the 2003 European Electronics Awards, Component Product of the Year, Fujitsu on 5 Dec 2006, announced the new MB86065 14-bit 1.3GSa/s DAC. The significant increase in conversion rate to 1.3GSa/s enables direct-IF frequencies to be pushed - and guaranteed - above 400MHz, widening the resulting spurious-free generating region and relaxing subsequent filtering requirements.
