Performance Characteristics
Description
Vectron's FX-104 is a SAW based frequency translator
which is used to translate any input frequency such as
8 kHz, 1.544 MHz, 2.048 MHz, 19.440 MHz etc. to any
specific frequency from 170 MHz to 777.6 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-104 also has the ability to translate any of 1 to
4 different input frequencies to one common output fre-
quency, such as input frequencies of 8 kHz and 1.544
MHz and 19.44 MHz and any other frequency between
333 Hz and 170 MHz translating them to any specific
output frequency from 170 MHz to 777.600 MHz.
The "Input Frequency tracking capability" is the total
amount of input frequency deviation in which the FX-
104 is guaranteed to track or translate. As an example,
a typical input clock would be 8 kHz 20 ppm. The FX-
104 is guaranteed to track at least 40 ppm of error over
temperature/ aging/ power 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 external circuitry (analog
comparators or an A/D converter plus a processor) to
detect when the control voltage is getting close to the
limits of the pull range.

Input Frequency - The FX-104 series AC couples the input, this means the unit is capable of
handling HCMOS, LvHCMOS, PECL and LvPECL input signals.
(For Input Frequencies below 1 MHz only HCMOS and LvHCMOS are supported)

(Output)
Under locked conditions, should be >0.3V and <3.0V for the 3.3 volt option or >0.5V and

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)
