Timing
Optimux-XLT1
Optimux-XLT1 can work with an internally generated clock (internal oscillator).
Loopback timing can be used in those systems that require a one-source clock.
High Speed Interface
The high-speed (HS) modules support the following timing modes:
• 4HSx1.5M – Internal, external and loopback timing
Figure 1-3 through Figure 1-7 show the different timing modes supported by the
HS modules.
