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 frequency, 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 FX104 is guaranteed to track or translate. As an example, a typical input clock would be 8 kHz ±20 ppm. The FX104 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.

(For Input Frequencies below 1 MHz only HCMOS and LvHCMOS are supported) Ground Lock Detect Logic “1” indicates a locked condition Logic “0” indicates that no input signal is present or the input signal has moved out of the lock range. PLL/ VCXO control voltage Under locked conditions, should be >0.3V and 0.5V and
