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.
