ICS2059-02

Clock Multiplier and Jitter Attenuator

Description

Features

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.

• Excellent jitter attenuation for telecom and video

clocks

• 2:1 Input MUX for input reference clocks

• No switching glitches on output

• VCXO-based clock generation offers very low jitter

and phase noise generation

• Output clock is phase and frequency locked to the

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.

selected input reference clock

• Fixed input to output phase relationship

• +115 ppm minimum crystal frequency pullability

range, using recommended crystal

• Industrial temperature range

• Low power CMOS technology

• 16-pin TSSOP package

• Single 3.3 V power supply
