FX-102 Frequency Translator
Description
Vectron's FX-102 is a crystal 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 77.76 to 170 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-102
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 translating them to any specific output fre-
quency from 77.76 MHz to 170 MHz.
The "Input Frequency tracking capability" is the total
amount of input frequency deviation in which the FX-102
is guaranteed to track or translate. As an example, a typ-
ical input clock would be 8 kHz ±20 ppm.The FX-102 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 compara-
tors or an A/D converter plus a processor) to detect
when the control voltage is getting close to the limits of
the pull range.
