GENERAL DESCRIPTION
The ABFT series is an Ultra Low Jitter VCXO based frequency translator; ideally suited to improve Jitter characteristics of the input signal. This device is
designed to provide input clock smoothing - while providing Phase and Frequency Locked higher frequency translated output.
Typical application will take a 10MHz reference frequency and phase & frequency lock it to either a 20MHz or a 40MHz Low Jitter VCXO. The implemented
technology significantly attenuates the jitter content of the 10MHz reference signal; while keeping the higher frequency RF Output - Frequency and Phase
Coherent with the input 10MHz reference signal.

(Note # 1):The frequency stability over temperature of the ABFT device is greatly dependant on the short term perturbations of the input reference signal.
(Note # 2):The Aging characteristics of the Quartz used inside the ABFT solution are such that, the stand-alone aging will not exceed ±12.00 ppm over a
10-year product life; referenced to the initial measured frequency post reflow in end application
