     3 As of AMC13XG firmware version 0x2257, please note the following change:
     4
     5 "The TTS output clock frequency in loop back mode is now 160.31MHz and
     6 very close to four times that of the actual TTC clock. The output of TTS in
     7 loop back mode is not an 80MHz clock any more, but a true TTC stream with !BcntRes"
     8
    19This is a small board which converts an electrical clock signal into an optical clock signal for use in AMC13 test stands.  The PCB layout was done with ExpressPCB.
