Description

The DAC3174 is a dual channel 14-bit, 500 MSPS digital-to-analog converter (DAC). The DAC3174 uses a 14-bit wide LVDS digital bus with 1 or 2 independent data clocks for flexibility in providing each channel’s data from different data sources. An input FIFO allows independent data and sample clocks.

FIFO input and output pointers can be synchronized across multiple devices for precise signal synchronization. The DAC outputs are current sourcing and terminate to GND with a compliance range of –0.5 to 1V. DAC3174 is pin compatible with the dual-channel, 12-/10-bit, 500 MSPS digital-to analog converter DAC3164/DAC3154 and single-channel, 14-/12-/10-bit, 500 MSPS digital-to-analog converter DAC3171/DAC3161/DAC3151.
