Chapter 5. Configuration Menu61200410L1-1 ESULT User Manual 5-5Network TimingThe network is the source of timing. The received dataclocking is looped back to the network where it is used todetermine the transmission timing. This option is alsoreferred to as looped timed as the transmission clock isderived from the received clock. See Figure 5-3..Figure 5-3. Network Timed Clock SourceInternal TimingThe ESU LT is the source of timing. The ESU LT is configuredto use its own internal oscillator as the source of timing.Applications include private line driver circuits where oneend is set to network and the other to internal.See Figure 5-4.Figure 5-4.
