Jitter can be cause by: poor decoupling to the Vcc and GND, signal source with heavy jitter, slow edge rate which will provide additional time to introduce jitter to the signal. Additional information can be found in Application Note 24: Designing for Minimal Jitter when using Clock Buffers
There are several types of jitter, but the main ones are: cycle-to-cycle jitter, period jitter, half period jitter, and peak-to-peak jitter. Jitter terminology can be found in AB36: Jitter Measurement Techniques at Application Brief No. 36 or Application Note No. 27.
TCXO means "Temperature Compensated Crystal Oscillator" A TCXO is essentially a quartz crystal integrated with compensation electronic circuitry sensitive to temperature variation. The compensation circuitry helps TCXO maintain high frequency stability over temperature (0.5ppm - 5ppm)
Cycle-to-cycle jitter is the difference in the clock's period between two consecutive cycles and is expressed in units of + pico-seconds. This is because it can be either leading or lagging from the ideal output waveform.
FCP is Frequency Control Product. They include crystals, crystal oscillators (XO), voltage control oscillators (VCXO), and TCXO. XO has IC and crystal integrated together as a component for quality easy use in system designs.

Half-Period Jitter is the measure of maximum change in a clock's output transition from its ideal position during one-half period. It is measured as: tjit(half-period) = thalf-period n – 1/2 ƒo, where ƒo is the frequency of the input signal.
All Pericom's products that are not lead-free are composed of 85% Sn and 15% Pb. For lead-free products, they are composed of 100% matte Sn. Lead-free products are marked and ordered with the letter "E" suffix at the end of the part number.
