1. The 2 MHz RCOsc should not be used as reference clock of PLLs. The 160 MHz oscillator should
be used instead for better PLL input jitter immunity.
2. Input jitter is additive to DLL output jitter. It should not exceed the maximum DLL input jitter
allowed. Refer to Table 5-19 for information on jitter specications.
3. When cascading DLL into PLL, DLL output frequency should be limited such that the PLL
input jitter requirement is met. Refer to Table 5-18 and Table 5-19 for information on jitter
specications.
