Zusammenfassung:	Systems for synchronizing downhole subs are disclosed. Some system embodiments may include a first downhole sub including a clock signal generator configured to generate an unmodified clock signal. The first downhole sub may also include a modification circuit configured to modify the clock signal. The system may also include a second downhole sub comprising a phase-locked loop circuit configured to receive as input the modified clock signal and output a second clock signal synchronous with the unmodified clock signal.
