DMTD or dual mixer time difference.
An all digital version (DDMTD like that used in CERN's White Rabbit) is 
also possible
3 (and M) input versions are also feasible.
Either an FPGA or a CPD plus a microprocessor are required to ensure low 

Sub 10ps resolution is readily achievable without significant difficulty.
