### Description

We studied the performance of a MCP-PMT with $2\times2$ matrix anode pixels fabricated by Xi'an Institute of optics and precision mechanics of CAS. The test result shows that the gain of the MCP-PMT remains stable up to $1\times10^{7}$. And the time resolution of single photoelectron (SPE) is better than 60ps ($\sigma$). The Cross-talk phenomenon among adjacent pixels which deteriorates the high time performance was also studied. We have developed an electronic model to explain its generation mechanism and suppress the crosstalk-over-signal amplitude ratio from 20% to lower than 5%. Furthermore, this mechanism has a universality that can also be applied in other multi-anode MCP-PMT Hamamatsu R10754.
