FX-101 Frequency Translator
Description
Vectron's FX-101 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 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
translating them to an output frequency up to 77.76 MHz.
The "Input Frequency tracking capability" is the total
amount of input frequency deviation in which the FX-101
is guaranteed to track or translate. As an example, a typ-
ical input clock would be 8 kHz ±20 ppm.The FX-101 is
guaranteed to track at least ±50 ppm of error over tem-
perature/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 con-
trol voltage is getting close to the limits of the pull range.
