DESCRIPTION
The DAC3283 is a dual-channel 16-bit 800 MSPS
digital-to-analog converter (DAC) with an 8-bit LVDS
input data bus with on-chip termination, optional 2x-
4x interpolation filters, digital IQ compensation and
internal voltage reference. The DAC3283 offers
superior linearity, noise and crosstalk performance.
Input data can be interpolated by 2x or 4x through
on-chip interpolating FIR filters with over 85 dB of
stop-band attenuation. Multiple DAC3283 devices can
be fully synchronized.
The DAC3283 allows either a complex or real output.
An optional coarse mixer in complex mode provides
frequency upconversion and the dual DAC output
produces a complex Hilbert Transform pair. The
digital IQ compensation feature allows optimization of
phase, gain and offset to maximize sideband rejection
and minimize LO feed-through of an external
quadrature modulator performing the final single
sideband RF up-conversion.
The DAC3283 is characterized for operation over the
entire industrial temperature range of –40°C to 85°C
and is available in a 48-pin 7×7mm QFN package.
