FX-104-DFC-D168

FX-104-DFC-D168 is one of the FX-104 series.Vectron's FX-104 series is a SAWs 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 series 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 1.544MHz 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 series 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.

Features of the FX-104 series are:(1)Output frequencies up to 777.60 MHz;(2)Jitter Generation OC-192 compliant;(3)Jitter transfer per GR-253-CORE;(4)Single 5 or 3.3 Vdc supply;(5)Locked to specified Input frequency, e.g. 8 kHz;(6)1" x 0.8" x 0.25", Surface Mount (FR4 base).
