| Abstract: |
| This paper describes a high-speed data acquisition system composed of ECL logic and TTL logic devices, which can sample and store data with 400MHz clock. This system can be accomplished easily and work stably. The performance test results show that the ENOB is more than 6 bits,which satisfies the application requirement.The system can find applications in the field of high-speed digital signal processing. |
