DescriptionThe DAC5675Aisa 14-bit resolution high-speed
digital-to-analog converter. The DAC5675A is
designed for high-speed digital data transmissionin communication systems, high- synthesis (DDS), andin test and measurement has excellent spurious- high well-suited and CDMA- (BTSs).

with low noise levels; thatis, with low electromagnetic
interference (EMI). LVDSis typically implementedin
low-voltage digital CMOS processes, makingit the
ideal technology for high-speed interfacing between
the DAC5675A and high-speed low-voltage CMOS
ASICsor FPGAs. The DAC5675A current-sink-array
architecture supports update ratesofupto 400MSPS.
On-chip edge-triggered input latches provide for
minimum setup and hold times, thereby relaxing
interface timing.
