Typical Phase Noise and Jitter Measurements
Jitter Results
Jitter measurements were performed on a Lecroy Wavemaster 8600A oscilloscope. The measurements
were recorded by testing the devices on an evaluation board with an AC coupled output. The evaluation
board was connected to the 8600A with an SMA bullet and 90k samples were taken. The values in the
table represent typical values and are in the units of pS.
Period Jitter: Period jitter compares the length of each cycle to the average period of an ideal clock
using the long term averaging frequency.
Cycle to Cycle Jitter: Cycle to cycle jitter compares the difference in the cycle length of adjacent cycles.
Time Interval Error Jitter: TIE Jitter is the variation in the clock’s transition from its ideal position over
many cycles.
Also included is the intgrated jitter for the 12 kHz to 20 MHz offset band, using an Agilent E5052A.

Typical Phase Noise for the VCC1 Series
Phase Noise Results
Phase noise measurements were performed on an Agilent E5052A signal source analyzer (SSA). The
E5052A has a phase noise to jitter integration calculation feature and devices were characterized in the
12kHz-20MHz band (except for the lower frequencies where the equipment limitations prevented
measurement to 20 MHz – see graphs for frequency band). Please contact Vectron for other offset
integration bands.
