SLAS749D March 2011 – September 2015 DAC3484
The DAC3484 is a very low power, high dynamic range, quad-channel, 16-bit digital-to-analog converter (DAC) with a sample rate as high as 1.25 GSPS.
The device includes features that simplify the design of complex transmit architectures: 2x to 16x digital interpolation filters with over 90dB 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, phase and group delay between channels in direct up-conversion applications.
Digital data is input to the device through a 16-bit LVDS data bus with on-chip termination. The device includes a FIFO, data pattern checker and parity test to ease the input interface. The interface also allows full synchronization of multiple devices.
Very low power, small size, superior crosstalk, high dynamic range and features of the DAC3484 are an ideal fit for systems with multiple transmit channels.
