ADC12xJ1600-Q1 is a family of quad, dual and single channel, 12-bit, 1.6 GSPS analog-to-digital converters (ADC). Low power consumption, high sampling rate and 12-bit resolution makes the ADC12xJ1600-Q1 ideally suited for light detection and ranging (LiDAR) systems. ADC12xJ1600-Q1 is qualified for automotive applications.Full-power input bandwidth (-3 dB) of 6 GHz provides flat frequency response for frequency modulated continuous wave (FMCW) LiDAR systems and provides a narrow impulse response for pulse-based systems. The full-power input bandwidth also enables direct RF sampling of of L-band and S-band.A number of clocking features are included to relax system hardware requirements, such as an internal phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO) to generate the sampling clock. Four clock outputs are provided to clock the logic and SerDes of the FPGA or ASIC. A timestamp input and output is provided for pulsed systems.JESD204C serialized interface decreases system size by reducing the amount of printed circuit board (PCB) routing. Interface modes support from 2 to 8 lanes (dual and quad channel devices) or 1 to 4 lanes (for the single channel device), with SerDes baud-rates up to 17.16 Gbps, to allow the optimal configuration for each application.
