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.
The device is available in a QFN-64 PowerPAD™
package is specified over the full industrial
temperature range (–40°C to 85°C).
