... All loop filter and analog isolation components should be tied as close to the package as possible. Stray current passing through the parasitics of long traces can cause undesirable voltage transients at the LF pin. b. The 10µF low frequency bypass capacitor and the 0.1µF high frequency bypass capacitor form a wide bandwidth filter that will minimize the 388915T's sensitivity to voltage transients from the system digital V supply and ground planes ...

... IDT74FCT388915T 3.3V LOW SKEW PLL-BASED CMOS CLOCK DRIVER (3-STATE) The frequency relationship shown here is applicable to all Q outputs (Q0, Q1, Q2, Q3 and Q4). 1:2 INPUT TO "Q" OUTPUT FREQUENCY RELATIONSHIP In this application, the Q/2 output is connected to the FEEDBACK input. The internal PLL will line up the positive edges of Q/2 and SYNC, thus the Q/2 frequency will equal the SYNC frequency ...
