Typical Performance Characteristics
Figures 1,2,3 and 4 show typical phase noise performance plots for 156.25 MHz, 150MHz, 125M, and 100MHz clock out-
puts respectively. The data was taken using the industry standard Agilent E5052B instrument. The integration range is the
widely referenced 12KHz to 20MHz range most often used in WAN applications.
