Recommended Reflow Profile
NOTE: The FX-100 series should not be subjected to a wash process that will immerse it in solvents. NO CLEAN is the rec-
ommended procedure. The FX-100 series has been designed for pick and place reflow soldering. The suggested reflow pro-
file is shown above. The FX-100 series may be reflowed once, and should not be reflowed in the inverted position.

Standard Shipping Method
The Standard ship method for volume production of the
FX-100 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.
Handling Precautions
Although protection circuitry has been designed into this ESD voltage thresholds are dependent on the circuit para-
device, proper precautions should be taken to avoid expo- meters used to define the mode. The HBM ESD thresh-

Typical Application
All components outside the dotted line box are user supplied components. This is just one possbile
configuration of the FX-102. For additional information about your specific needs, please contact our factory.
Output Load Configuration
*Note: VI highly recommends either a linear
regulator or bypass capacitors; 10 uF, 0.1 uF
and a 100pF capacitor would be typical.
All components outside the dotted line box are user supplied components
and/or connections. This is just one possible configuration of the FX-102.

FAQ’s
Q: What are the different input frequencies that are available?
A: The FX-100 series is able to handle any input frequency between 8 kHz and 170 MHz.
(A list of standard frequencies is available on pages 9 & 10.)
Q: How many different input frequencies can a specific FX-102 accept?
A: Each FX-102 can be programmed to accept up to 4 different frequencies.
Q: If there is only one input pin, how can your unit accept 4 different frequencies?
A: The user is required to supply a multiplexer which would switch between the different input
frequencies.The multiplexers’ select pins would need to be sync’d to the select pins of the FX-102.
(See TheTypical Application illustrated on page 6.)
Q: Can a single FX-102 handle an application for 4 input frequencies of 8 kHz, 19.44, 77.76 and 155.52 MHz
all being translated to 155.52 MHz, with the 155.52 MHz input being LvPECL and the others HCMOS?
A: Yes; since the FX-102 AC couples the input signal, this combination can be supported.
Q: What is the lock time for the FX-102?
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.
Q: I asked for a FX-102-DFC-A2S6 with 19.44 and 155.52 MHz for the input frequencies and was given a
Source Control Drawing (SCD) number of FX-102-DFC-S5999. Why was a new number assigned?
A: Whenever there are multiple input frequencies, we need to assign a SCD for the unit so that we can
include a table indicating what the logic levels need to be on pins 12 and 13 to control the unit per
the correct input frequency.
Q: What are the exact jitter transfer specs that the FX-102 series meets?
A: The FX-102 meets the stringent jitter transfer specs in GR-253 for Category II jitter (Section 5.6.2.1.2)
for all OC-n levels.
Q: My circuit card is already laid out for the FX-104, Is the FX-102 footprint compatible?
A: Yes;The FX-102 package is a drop in replacement for the FX-104 package.The only difference is in
the logic level for the Output Disable/Enable pin. They are opposite between the FX-102 and FX-104.
However letting pin 8 float will allow both units to be enabled.
Q: What type of noise on the supply line can the FX-102 suppress?
A: The FX-102 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 on your supply line.

Other Standard Input / Output Combinations
The combinations above are just a small sample of what is possible with the FX-102 series.
This series is capable of translating up and down in frequency. Virtually all input frequencies
between 8 kHz and 170 MHz can be supported.
The FX-102 uses Vectron International’s J-type VCXO and as such can support any output
frequency that is available with the J-Type.
Vectron International will support all FEC rates for SONET, 10 GigE and 10.3125 GigE applications.
If you do not see a frequency option listed that you need please contact the factory.
When ordering FEC rates, we ask that you also include the FEC ratio
(e.g. 255/237 x OC-3, 237/236 x OC-3,etc....) for both the input and output frequencies.
