描述
The 2059-02 is a VCXO (Voltage Controlled Crystal Oscillator) based clock multiplier and jitter attenuator designed for system clock distribution applications. This monolithic IC, combined with an external inexpensive quartz crystal, can be used to replace a more costly hybrid VCXO retiming module. A dual input mux is also provided. By controlling the VCXO frequency within a phase-locked loop (PLL), the output clock is phase and frequency locked to the input clock. Through selection of external loop filter components, the PLL loop bandwidth and damping factor can be tailored to meet system clock requirements. A loop bandwidth down to the Hz range is possible.
