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
device, proper precautions should be taken to avoid
exposure to electrostatic discharge (ESD) during han-
dling and mounting. VI employs a human-body model
(HBM) for ESD-susceptibility testing and protection
design evaluation.
ESD voltage thresholds are dependent on the circuit
parameters used to define the mode. The HBM ESD
threshold presented here was obtained by using para-
meters where resistance = 1500 ohms, capacitance =

Typical Application
All components outside the dotted line box are user supplied components. This is just one possbile
configuration of the FX-101. 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-101.

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 and 10.)
Q: How many different input frequencies can a specific FX-101 accept?
A: Each FX-101 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-101.
(See TheTypical Application illustrated on page 6.)
Q: Can a single FX-101 handle an application for 4 input frequencies of 8 kHz, 19.44, 38.88 and 77.76 MHz
all being translated to 77.76 MHz, with the 77.76 MHz input being LvPECL and the others HCMOS?
A: Yes; since the FX-101 AC couples the input signal, this combination can be supported.
Q: What is the lock time for the FX-101?
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-101-DFC-A2S2 with 19.44 and 155.52 MHz for the input frequencies and was given a
Source Control Drawing (SCD) number of FX-101-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-101 series meets?
A: The FX-101 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: Does the output frequency need to be 77.76 MHz?
A: No, the output frequency can be any frequency between 1.544 MHz and 77.76 MHz.
(A list of standard frequencies is available on pages 9 and 10.)
Q: What type of noise on the supply line can the FX-101 suppress?
A: The FX-101 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-101 series.
The FX-101 uses Vectron International’s V-type VCXO
and as such can support any output frequency that is
available with the V-Type. A list of available output fre-
quencies for the V-Type is provided below.
This series is capable of translating up and down in
frequency. Virtually all input frequencies between 8
kHz and 170 MHz can be supported.
