1 / 50 page DAC3283 www.ti.com SLAS693A – MARCH 2010 – REVISED APRIL 2010 Dual-Channel, 16-Bit, 800 MSPS, Digital-to-Analog Converter (DAC) Check for Samples: DAC3283 1 FEATURES APPLICATIONS • Cellular Base Stations • Dual, 16-Bit, 800 MSPS DACs • Diversity Transmit • 8-Bit Input LVDS Data Bus • Wideband Communications – Byte-Wide Interleaved Data Load • Digital Synthesis – 8 Sample Input FIFO – Optional Data Pattern Checker DESCRIPTION • Multi-DAC Synchronization The DAC3283 is a dual-channel 16-bit 800 MSPS • Selectable 2x-4x Interpolation Filters digital-to-analog converter (DAC) with an 8-bit LVDS – Stop-Band Attenuation > 85 dB input data bus with on-chip termination, optional 2x-4x interpolation filters, digital IQ compensation and • Fs/2 and ± Fs/4 Coarse Mixer internal voltage reference. The DAC3283 offers • Digital Quadrature Modulator Correction superior linearity, noise and crosstalk performance. – Gain, Phase and Offset Correction Input data can be interpolated by 2x or 4x through • Temperature Sensor on-chip interpolating FIR filters with over 85 dB of • 3- or 4-Wire Serial Control Interface stop-band attenuation. Multiple DAC3283 devices can be fully synchronized. • On-Chip 1.2-V Reference • Differential Scalable Output: 2 to 20 mA The DAC3283 allows either a complex or real output. An optional coarse mixer in complex mode provides • Single-Carrier TM1 WCDMA ACLR: 82 dBc at frequency upconversion and the dual DAC output fOUT = 122.88 MHz produces a complex Hilbert Transform pair. The • Low Power: 1.3 W at 800 MSPS digital IQ compensation feature allows optimization of • Space Saving Package: 48-pin 7×7mm QFN 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.
