Vectron's CS-300 is a SAW based Clock Smoother and Frequency Translator which is used to clean upnoisy input frequencies. This series can accept any input frequency from 10 MHz to 700 MHz and then cleans upup 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 f or 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.

FAQ s
Q1: What are the different input frequencies available? A: The CS-300 is able to handle any input frequency between 10 MHz and 700 MHz. (A list of standard frequencies is available on page 8.) Q2: How many different input frequencies can a specific CS-300 accept? A: Each CS-300 can be programmed to accept up to 2 different input frequencies. Q3: If there is only one set of input pins, how can your unit accept 2 different frequencies? A: The customer is required to supply a multiplexer which would switch between the different input frequencies. The multiplexersselect pin would need to be sync to d the select pin of the CS-300. Q4: What is the lock time for the CS-300? A: The exact lock time will depend on the specific input frequency. It should be noted that in all cases the lock time will be significantly less than 1 second. Q5: What type of noise on the supply line can the CS-300 suppress? A: The CS-300 is designed to clean up noise on the Input Clock Signal, it is not designed to clean up noisy power supplies. If excessive noise is present on the supply line it may degrade the output jitter performance. Additional external filtering may be required. Please consult with your power supply vendor on the best way to filter noise of your supply line.
