Description
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 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.
Features
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
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
