Time-interleaved Analog-to-digital Converter（TIADC）is an effective way to increase the sampling frequency of ADC, but the sampling time and relative error between the channels seriously affect the system performance. In this paper, we proposed a photonic time-interleaved analog-to-digital conversion (TIADC) scheme by exploring optical clock distribution. A proof-of-concept experiment with a four-channel TIADC was implemented and demonstrated. Experimental results show that the optical clock distribution system can offer a four-channel clock with low jitter. These results are very encouraging toward the development of optical clock distribution based electrical systems in the practical applications.
