From ASIC to FPGA

          168 * 192 * 12 bit * 14/12 (encoding) = 451,584 bit/frame

@35 kHz framerate: 451,584 bit/frame * 35 kHz = 15.8 Gbps

@100 kHz framerate: 451,584 bit/frame * 100 kHz = 45.2 Gbps


From FPGA to PC

168 * 192 * 12 bit * 66/64 (PGP encoding) = 399,168 bit/frame

@32k - 1 ASIC (35kHz/100kHz): 14 Gbps / 40 Gbps

@140k - 4 ASIC (35kHz/100kHz): 56 Gbps / 160 Gbps

@1M - 30 ASIC (35kHz/100kHz): 420 Gbps / 1.19 Tbps

@1.1M - 36 ASIC (35kHz/100kHz): 504 Gbps / 1.44 Tbps

@4M - 144 ASIC (35kHz/100kHz): 2 Tbps/ 5.76 Tbps

@16M - 576 ASIC (35kHz/100kHz): 8.1 Tbps / 23 Tbps
