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: 2× to 16× 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.
The device is characterized for operation over the entire industrial temperature range of –40°C to 85°C and is available in a very-small 88-pin 9x9mm WQFN package or 196-ball 12×12mm NFBGA package.
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.

The design is for a small cell base station development platform. It provides two real receive paths, two complex transmit paths, and a shared real feedback path. This design has macro basestation performance, but with small cell base station footprint. The current design handles (...)
The TSW308x is an example design of a wideband digital to RF transmit solution capable of generating 600 MHz of contiguous RF spectrum. The system provides a reference on how to use the DAC34x8x, TRF3705 IQ modulator and LMK0480x to achieve this. This reference EVM coupled with a (...)
The analog interface circuits in this reference design are often used between current-source based digital-to analog converters (DAC) and quadrature modulators. While the DAC348x is used as an example of a TI high-speed DAC, the circuits can be applied to other current-source based converters with (...)
