Texas Instruments DAC3xJ84 Quad-Channel 16-Bit DACs
Texas Instruments DAC3xJ84 Quad-Channel 16-Bit Digital-to-Analog Converters (DACs) are a low power, 16-bit, quad-channel, 1.6/2.5 GSPS digital-to-analog converter (DAC) with JESD204B interface. Digital data is input to the device through 1, 2, 4 or 8 configurable serial JESD204B lanes running up to 12.5Gbps with on-chip termination and programmable equalization. The interface allows JESD204B Subclass 1 SYSREF based deterministic latency and full synchronization of multiple devices. The device includes features that simplify the design of complex transmit architectures. Fully bypassable 2x to 16x digital interpolation filters with over 90dB of stop-band attenuation simplify the data interface and reconstruction filters. An on-chip 48-bit Numerically Controlled Oscillator (NCO) and independent complex mixers allow flexible and accurate carrier placement.
