Multi-wire drift chamber at external target experiment in HIRFL-CSR measures drift time of charged particles to obtain the track information. A 64-channel TDC module hosting high density connectors and high performance TDC chips (HPTDC) are used to perform the time digitization. Data of the module is transferred to computer through PXI bus.The test results show that a 100 ps resolution has been achieved.
