Description
Vectron's FX-101 is a crystal based frequency tra n s l a t o r
which is used to translate any input frequency such as 8
kHz, 1.544 MHz, 2.048 MHz, 19.440 MHz etc.to any spe-
cific frequency less than or equal to 77.76 MHz. The input
frequency does not have to be a 50/50% duty cycle and
as an example can be an 8 kHz signal with a logic high
"on time" of only 1us, such as a BITS clock . The FX-101
also has the ability to translate any of 1 to 4 different input
frequencies to one common output frequency, such as
input frequencies of 8 kHz and 1.544 MHz and 19.44 MHz
and any other frequency between 8 kHz and 170 MHz
t ranslating them to an output frequency up to 77.76 MHz.
The "Input Frequency tra cking capability" is the total
amount of input frequency deviation in which the FX-101
is guaranteed to tra ck or tra n s l a t e. As an ex a m p l e, a typ-
ical input clock would be 8 kHz 20 ppm.The FX-101 is
g u a ranteed to tra ck at least 50 ppm of error over tem-
p e ra t u r e / a g i n g / p ower supply and is more than twice what
most applications require. The PLL control voltage is
brought out through a 470K ohm resistor.This would allow
for the use of ex t e rnal circuitry (analog comparators or an
A/D conve rter plus a processor) to detect when the con-
trol voltage is getting close to the limits of the pull ra n g e.

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
d ev i c e, proper precautions should be taken to avo i d
exposure to electrostatic discharge (ESD) during han-
dling and mounting. VI employs a human-body model
(HBM) for ESD-susceptibility testing and protection
design eva l u a t i o n .
ESD voltage thresholds are dependent on the circuit
p a rameters used to define the mode. The HBM ESD
threshold presented here was obtained by using para-
meters where resistance = 1500 ohms, capacitance =
100pf)

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 The Typical 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.

The combinations above are just a small sample of
what is possible with the FX-101 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-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.
