ICS2059-02

Stresses above the ratings listed below can cause permanent damage to the ICS2059-02. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.

The ICS2059-02 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 of the ICS2059-02 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.
