An example list of LiDAR system requirements and the resulting digitizer requirements is given in Table 10-1. The example system requirements are for a mechanically rotating LiDAR system using a spinning mirror to cover the horizontal (azimuth) field-of-view and parallel receivers (photodiodes) to cover the vertical (elevation) field-of-view. The scan time requirement dictates that four vertical points are captured in parallel which requires four ADC channels and therefore a 16:1 photodiode to ADC mux ratio. The long 200 meter range for a 10% reflectivity target requires high performance and therefore a 12-bit ADC is chosen. The minimum pulse width of 5 ns, for high spatial resolution, requires a sampling rate of 1 GSPS in order to get 5 samples of each returning pulse. Low cost and small size are important to enable high volume production and a quad channel ADC with integrated clocking features help drive down these important metrics. Other considerations include the maximum SerDes rate supported by the FPGA and number of lanes. Assume the FPGA has 4 SerDes lanes that support up to 12.5 Gbps. For this reason, JMODE 8 is chosen.
