COMMUNICATIONS CLOCK JITTER ATTENUATOR DATASHEET MK2058-01 The MK2058-01 is a VCXO Voltage Controlled Crystal Oscillator based clock 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. The device accepts and outputs the same clock frequency in selectable ranges covering 4 kHz to 27 MHz. 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.

DATASHEET

MK2058-01

The MK2058-01 is a VCXO Voltage Controlled Crystal Oscillator based clock 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. The device accepts and outputs the same clock frequency in selectable ranges covering 4 kHz to 27 MHz. 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.
