The digital Quadrature • Multi-DAC Synchronization Modulator Correction (QMC) enables complete IQ compensation for gain, offset, phase and group delay • Selectable 2x, 4x, 8x, 16x Interpolation Filter between channels in direct up-conversion – Stop-Band Attenuation > 90 dBc applications. • Flexible On-chip Complex Mixing Digital data is input to the device through a 32-bit – Two Independent Fine Mixers with 32-bit wide LVDS data bus with on-chip termination. The NCOs wide bus allows the processing of very high – Power Saving Coarse Mixers: ± n×Fs/8 bandwidth signals. The device includes a FIFO, data pattern checker and parity test to ease the input • High Performance, Low Jitter Clock Multiplying interface. The interface also allows full PLL synchronization of multiple devices. • Digital I and Q Correction The device is characterized for operation over the – Gain, Phase, Offset, and Group Delay entire industrial temperature range of –40°C to 85°C Correction and is available in a 196-ball, 12x12mm, 0.8mm pitch • Digital Inverse Sinc Filters BGA package. • 32-Bit DDR Flexible LVDS Input Data Bus The DAC34H84 very low power, high bandwidth – 8 Sample Input FIFO support, superior crosstalk, high dynamic range and features are an ideal fit for next generation – Supports Data Rates up to 625 MSPS communication systems. – Data Pattern Checker – Parity Check Device Information(1) • Temperature Sensor PART NUMBER PACKAGE BODY SIZE (NOM) • Differential Scalable Output: 10mA to 30mA DAC34H84 NFBGA (196) 12.00 mm x 12.00 mm • 196-Ball, 12x12mm NFBGA (GREEN / Pb-Free) (1) For all available packages, see the orderable addendum at the end of the data sheet. 2 Applications Simplified Schematic • Cellular Base Stations • Diversity Transmit • Wideband Communications 3 Description The DAC34H84 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 90 dB of stop-band attenuation simplify the data interface and reconstruction filters. Independent complex mixers allow flexible carrier placement. 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
