Beschreibung

ADC09QJ1300-Q1 is a quad channel, 9-bit, 1.3 GSPS analog-to-digital converter (ADC). Low power consumption, high sampling rate and 9-bit resolution makes the ADC09QJ1300-Q1 ideally suited for light detection and ranging (LiDAR) systems and handheld test equipment. ADC09QJ1300-Q1 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 up to 4 GHz.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 and SerDes linerates up to 17.16 Gbps to allow the optimal configuration for each application.
