The Fujitsu MB86065 is a 14-bit 1+GSa/s digital to analog converter (DAC), delivering exceptional dynamic performance and backwards compatibility with 'DAC A' of the MB86064. The high performance DAC core is capable of generating multi-standard, multi-carrier communication transmit signals, suitable for existing and future systems. DAC data is input via a high-speed LVDS port. This operates 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 is clocked at half the DAC conversion rate.
