1 / 106 page  DAC3482 16-bit DAC 16-bit DAC xN xN RF Product Folder Sample & Buy Technical Documents Tools & Software Support & Community DAC3482 SLAS748F – MARCH 2011 – REVISED AUGUST 2015 DAC3482, Dual-Channel, 16-Bit, 1.25 GSPS Digital-to-Analog Converter (DAC) 1 Features 3 Description The DAC3482 is a very low power, high dynamic 1 • Very Low Power: 900 mW at 1.25 GSPS, Full range, dual-channel, 16-bit digital-to-analog converter Operating Conditions (DAC) with a sample rate as high as 1.25 GSPS. • Multi-DAC Synchronization The device includes features that simplify the design • Selectable 2x, 4x, 8x, 16x Interpolation Filter of complex transmit architectures: 2x to 16x digital – Stop-Band Attenuation > 90 dBc interpolation filters with over 90 dB of stop-band attenuation simplify the data interface and • Flexible On-Chip Complex Mixing reconstruction filters. A complex mixer allows flexible – Fine Mixer with 32-Bit NCO carrier placement. A high-performance low jitter clock – Power Saving Coarse Mixer: ± n×Fs/8 multiplier simplifies clocking of the device without • High Performance, Low Jitter Clock Multiplying significant impact on the dynamic range. The digital Quadrature Modulator Correction (QMC) enables PLL complete IQ compensation for gain, offset, phase, • Digital I and Q Correction and group delay between channels in direct up- – Gain, Phase, Offset, and Group Delay conversion applications. Correction Digital data is input to the device through a flexible • Digital Inverse Sinc Filter LVDS data bus with on-chip termination. Data can be • Flexible LVDS Input Data Bus input either word-wide or byte-wide. The device includes a FIFO, data pattern checker and parity test – Word- or Byte-Wide Interface to ease the input interface. The interface also allows – 8 Sample Input FIFO full synchronization of multiple devices. – Data Pattern Checker The device is characterized for operation over the – Parity Check entire industrial temperature range of –40°C to 85°C • Temperature Sensor and is available in a very-small 88-pin 9x9mm WQFN-MR package or 196-ball 12x12mm NFBGA • Differential Scalable Output: 10 mA to 30 mA package. • Multiple Package Options: 88-Pin 9x9mm WQFN- MR and 196-ball 12mmx12mm NFBGA (GREEN / Very low power, small size, superior crosstalk, high Pb-Free) dynamic range, and features of the DAC3482 make it an ideal fit for today’s communication systems. 2 Applications Device Information(1) • Cellular Base Stations PART NUMBER PACKAGE BODY SIZE (NOM) • Diversity Transmit WQFN-MR (88) 9.00 mm x 9.00 mm DAC3482 • Wideband Communications NFBGA (196) 12.00 mm x 12.00 mm (1) For all available packages, see the orderable addendum at the end of the datasheet.
