DESCRIPTION
The DAC34SH84 is a very low-power, high-dynamic range, quad-channel, 16-bit digital-to-analog converter (DAC) with a sample rate as high as 1.5 GSPS.
The device includes features that simplify the design of complex transmit architectures: 2× to 16× digital interpolation filters with over 90 dB of stop-band attenuation simplify the data interface and reconstruction filters. Independent complex mixers allow flexible carrier placement. A high-performance
low-jitter clock multiplier simplifies clocking of the device without significant impact on the dynamic
range. The digital quadrature modulator correction (QMC) enables complete IQ compensation for gain,
offset and phase between channels in direct upconversion applications.
