CS300 Datasheet, PDF (2/8 Pages) Vectron International, Inc – Clock Smoother

Vectron's CS-300 is a SAW based Clock Smoother and Frequency Translator which is used to
“clean up“noisy input frequencies. This series can accept any input frequency from 10 MHz to
700 MHz and then “cleans up“up the signal to provide an ultra low jitter output signal. The output
jitter of this unit is well below the requirements of OC-192.
The CS-300 also has the ability to translate either one or two different input frequencies between
10 MHz and 700 MHz to one common output frequency, such as input frequencies of 622.08 MHz
and 666.5143 MHz translated to an output frequency of 622.08 MHz. This unit is of particular
interest to those working with FEC applications or needing to switch between 10G and OC-192.
The "Input Frequency Tracking Capability" is the total amount of frequency deviation on the input
signal that the CS-300 is guaranteed to track. As an example, a typical input clock would be
622.08 MHz ± 20 ppm. The CS-300 is guaranteed to track at least ±40 ppm of error over
temperature/ aging/ power supply and is more than twice what most applications require.
