R1: Loop filter resistor, 680 Ω.
R2: Current-limiting resistor; generally, a 100-Ω to 500-Ω resistor is used, but it depends on the crystal resonator.
R3, R4: Coax input termination resisters, 75 Ω.
C1, C2: 4.7-mF electrolytic capacitor is recommended for 3-Hz cutoff frequency.
C3, C7, C12, C13: 0.1-mF ceramic capacitor and 10-mF electrolytic capacitor, depending on the power supply.
C4: 0.1-mF ceramic capacitor and 10-mF electrolytic capacitor is recommended.
C5: Loop filter capacitor, 0.068 mF.
C6: Loop filter capacitor, 0.0047 mF.
C8, C9: OSC load capacitor; generally, a 10-pF to 30-pF capacitor is used, but it depends on the crystal resonator
and PCB layout.
C10, C11: DC blocking capacitor for coax input, 0.1 mF.
X1: Crystal resonator. Use a 24.576-MHz fundamental resonator when the XTI clock source is needed.
