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.

NOTE: The CS-300 should not be subjected to a wash process that will immerse it in solvents. NO CLEAN is the recommended
procedure.
The CS-300 has been designed for pick and place reflow soldering. The suggested reflow profile is shown above.
The CS-300 may be reflowed once, and should not be reflowed in the inverted position.

The Standard ship method for volume production of the CS-300 series is in a matrix tray. These
trays are 100% recyclable. The trays also offer the added feature that they can be continuously
feed into a pick-n-place machine eliminating the down time required with tape-n-reel.
Although protection circuitry has been
designed into this device, proper precautions
should be taken to avoid exposure to
electrostatic discharge (ESD) during handling
and mounting. VI employs a human-body
model (HBM) and a charged-device model
(CDM) for ESD-susceptibility testing and
protection design evaluation. ESD voltage
thresholds are dependent on the circuit
parameters used to define the mode.
Although no industry-wide standard has been
adopted for the CDM, a standard HBM
(resistance = 1500 ohms, capacitance =
100pf) is widely used and therefore can be
used for comparison purposes. The HBM
ESD threshold presented here was obtained
by using these circuit parameters.
