128 / 164 page  ST72324Jx ST72324Kx 128/164 CLOCK CHARACTERISTICS (Cont’d) 12.6.5 PLL Characteristics Note: 1. Data characterized but not tested. The user must take the PLL jitter into account in the application (for example in serial communication or sampling of high frequency signals). The PLL jitter is a periodic effect, which is integrated over several CPU cycles. Therefore the longer the period of the application signal, the less it will be impacted by the PLL jitter. Figure 68 shows the PLL jitter integrated on application signals in the range 125kHz to 2MHz. At frequen- cies of less than 125KHz, the jitter is negligible. Figure 68.
