3.0 Functional Block Diagram
3.1 Voltage-Controlled Crystal Oscillator (VCXO)
The VCXO provides a tunable, low-jitter frequency reference for the rest of the FS6128 system components. Loading capacitance for
the crystal is internal to the FS6128. No external components (other than the resonator itself) are required for operation of the VCXO.
Continuous fine-tuning of the VCXO frequency is accomplished by varying the voltage on the XTUNE pin. The value of this voltage
controls the effective capacitance presented to the crystal. The actual amount that this load capacitance change will alter the oscillator
frequency depends on the characteristics of the crystal as well as the oscillator circuit itself.
It is important that the crystal load capacitance is specified correctly to “center” the tuning range. See Table 5.
