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.

An example of implementing the high speed LVDS data interface using a Stratix™ FPGA has been documented by Altera. This reference design comprises two 14-bit parallel buses, each running at up to 800 million samples per second (MSPS). A key feature is the combination of the Stratix enhanced phase-locked loop (PLL) with the MB86064 loop-clock facility to maintain optimum clock-to-data timing.
