FX-104 Frequency Translator
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.
