For multi-channel high-speed Charge Couple Device (CCD) image data transmission, a new high-speed multi-spectral Time Delay Integrated CCD (TDICCD) image data transmission system was designed and applied successfully. Overall system design principle and realization in FPGA were introduced. Especially, the key technology such as Field Programmable Gate Array (FPGA) function division, time-division multiplexing storage and Low Voltage Differential Signaling (LVDS) interface were described in detail. Finally, 60 channels’ parallel image data of 5 TDICCD were converted into 7 channels serial image data. Experiments show that the system’s single channel output data rate is up to 1.38 Gbit/s, and total effective data output rate is up to 8.66 Gbit/s. The system works stably with high effective and transplantable property.
