IDT DAC1653Q-DAC1658Q Block Diagram


High-performance 16-bit Quad DAC, High Common Mode

The DAC1658Q is a high-speed, high-performance 16-bit quad channel digital-to-analog converter (DAC). The device provides sample rates up to 2.0 Gsps with selectable 2x, 4x and 8x interpolation filters optimized for multi carrier and broadband wireless transmitters. The DAC1658Q integrates a JEDEC JESD204B-compliant high-speed serial input data interface running up to 10 Gbps allowing dual channel input sampling at up to 1 Gsps over four differential lanes. It offers numerous advantages over traditional parallel digital interfaces. The DAC1658Q integrates a very low noise bypassable phase-locked loop (PLL), two embedded NCOs with 40-bit programmable frequency and  two embedded complex (IQ) digital modulators. It is configured with high output common mode from 2.8 to 3.0V.
