2.2.10. HD Tri-Level Genlock
Figure 2-11: Lock Diagram #4 - HD Tri-Level Genlock Operation
The 5601MSC can lock to several different HD analog tri-level signals. The main oscillator frequency is
locked to the rising edge of the tri-level waveform. The phase information provided by tri-level reference
signals is limited and each signal standard can only be used to deterministically phase lock standards
of a similar frame rate. Lock diagram #4 above gives an example for 1080i/59.94 tri-level sync. Refer to
Table 2-5 for a summary on the phase locking capability with other tri-level references.
