3.3 VOLT FRAME RATE COMMUNICATIONS PLL
VDD = 3.3 V, Ambient Temperature 0 to +70°C, unless stated otherwise
Note 1: All multipliers as shown in the table on page two are exact, and are stored in ROM on the chip.
The series-connected capacitor and resistor between CAP1 and CAP2 (pins 4 and 6) determine the dynamic
characteristics of the phase-locked loop. The capacitor must have very low leakage, therefore a high quality
ceramic capacitor is recommended. DO NOT use any type of polarized or electrolytic capacitor. The series
connected capacitor and resistor between CAP1 and CAP2 (pins 4 and 6) determine the dynamic characteristics of
the phase-locked loop. The capacitor must have very low leakage, therefore a high quality ceramic capacitor is
recommended. DO NOT use any type of polarized or electrolytic capacitor. Ceramic capacitors should have C0G or
NP0 dielectric. Avoid high-K dielectrics like Z5U and X7R; these and other ceramics which have piezoelectric
properties allow mechanical vibration in the system to increase the output jitter because the mechanical energy is
converted directly to voltage noise on the VCO input.
The values of the RC network determine the bandwidth of the PLL. The values of the loop filter components are
calculated using the constants K1 and K2 from the Loop Filter Constants table (page 7). The loop bandwidth is set
by the capacitor C and the constant K1 using the formula:
