The interface allows – 12.5 Gbps Maximum Bit Rate per Lane JESD204B Subclass 1 SYSREF based deterministic – Subclass 1 Multi-DAC Synchronization latency and full synchronization of multiple devices. • On-Chip Very Low Jitter PLL The device includes features that simplify the design • Selectable 1x -16x Interpolation of complex transmit architectures. Fully bypassable • Independent Complex Mixers with 48-bit NCO/ or 2x to 16x digital interpolation filters with over 90 dB of ±n×Fs/8 stop-band attenuation simplify the data interface and reconstruction filters. An on-chip 48-bit Numerically • Wideband Digital Quadrature Modulator Controlled Oscillator (NCO) and independent Correction complex mixers allow flexible and accurate carrier • Sinx/x Correction Filters placement. • Fractional Sample Group Delay Correction A high-performance low jitter PLL simplifies clocking • Multi-Band Mode: Digital Summation of of the device without significant impact on the Independent Complex Signals dynamic range. The digital Quadrature Modulator Correction (QMC) and Group Delay Correction (QDC) • 3/4-Wire Serial Control Bus (SPI) enable complete IQ compensation for gain, offset, • Integrated Temperature Sensor phase, and group delay between channels in direct • JTAG Boundary Scan up-conversion applications. A programmable Power • Pin-Compatible with Quad-Channel Amplifier (PA) protection mechanism is available to provide PA protection in cases when the abnormal DAC37J84/DAC38J84 Family power behavior of the input data is detected. • Power Dissipation: 1.8W at 2.8GSPS • Package: 10 mm x 10 mm, 144-Ball Flip-Chip Device Information(1) BGA PART NUMBER PACKAGE BODY SIZE (NOM) DAC39J84 FCBGA (144) 10.00 mm x 10.00 mm 2 Applications (1) For all available packages, see the orderable addendum at • Cellular Base Stations the end of the datasheet. • Diversity Transmit • Wideband Communications • Direct Digital Synthesis (DDS) instruments • Defense/Military • Millimeter/Microwave Backhaul • Automated Test Equipment • Cable Infrastructure 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.
