SI5341B 10 Independent Output Any-Frequency Clock Generator (PS
Reference Clock)
[Figure 2-1, callout 10]
• Clock generator: Silicon Labs SI5341B-B05071-GM
• Jitter: <100 fs RMS typical
• Differential and single-ended outputs
The SI5341B is a one-time programmable clock source. For more details refer to the SI5341B
data sheet [Ref 17] for more details. The clock circuit is shown in Figure 3-8.
