Two-channel time-to-digital converter

A two-channel time-to-digital converter based on the direct filling of the measured interval by the standard frequency generator pulses with counting them up afterwards is described. Maximum frequency of the code series generator F - 200 MHz (external generator). Number of bits in an output word -12, with the 12th bit being an indication of information. The series frequency differential nonlinearity of the converter F =200 MHz; -+0.5 per cent. The converter is made as a CAMAC module of a unit width. It can operate with the external information storage unit without communication with the crate dataway
