1 / 51 page  DAC3282 www.ti.com SLAS646A – DECEMBER 2009 – REVISED FEBRUARY 2010 16-Bit, 625 MSPS, 2x Interpolating, Dual-Channel Digital-to-Analog Converter (DAC) Check for Samples: DAC3282 1 FEATURES DESCRIPTION • Dual, 16-Bit, 625 MSPS DACs • 8-Bit Input LVDS Data Bus The DAC3282 is a dual-channel 16-bit 625 MSPS digital-to-analog converter (DAC) with an 8-bit LVDS – Byte-Wide Interleaved Data Load input data bus with on-chip termination, optional 2x – 8 Sample Input FIFO interpolation filter, and internal voltage reference. The – Optional Data Pattern Checker DAC3282 offers superior linearity, noise and crosstalk performance. • Multi-DAC Synchronization • Optional 2x Interpolation Filter Input data can be interpolated by 2x through an on-chip interpolating FIR filter with over 85 dB of • Zero-IF Sinc Correction Filter stop-band attenuation. Multiple DAC3282 devices can • Fs/2 and ± Fs/4 Coarse Mixer be fully synchronized. • Digital Offset Adjustment for LO Correction The DAC3282 allows either a complex or real output. • Temperature Sensor An optional coarse mixer in complex mode provides • 3- or 4-Wire Serial Control Interface frequency upconversion and the dual DAC output produces a complex Hilbert Transform pair. The • On Chip 1.2-V reference digital offset correction feature allows optimization of • Differential Scalable Output: 2 to 20 mA LO feed-through of an external quadrature modulator • Low Power: 950 mW at 625 MSPS, 845 mW at performing the final single sideband RF 500 MHz, Full Operating Conditions up-conversion. • Space Saving Package: 48-pin 7×7mm QFN The DAC3282 is characterized for operation over the entire industrial temperature range of –40°C to 85°C APPLICATIONS and is available in a 48-pin 7×7mm QFN package. • Cellular Base Stations • Diversity Transmit • Wideband Communications • Digital Synthesis spacer for space above the ordering information table spacer for space above the ordering information table ORDERING INFORMATION PACKAGE TRANSPORT TA ORDER CODE QUANTITY DRAWING/TYPE(1) (2) MEDIA DAC3282IRGZT RGZ / 48QFN Quad Flatpack 250 –40°C to 85°C Tape and Reel No-Lead DAC3282IRGZR 2500 (1) Thermal Pad Size: 5,6 mm x 5,6 mm (2) MSL Peak Temperature: Level-3-260C-168 HR 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
