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 155.52 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 up to any of 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 333 Hz and 155.52 MHz translating them to any specific output
frequency from 77.76 MHz to 155.52 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 typical 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 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.
