Frequency Translator-Evaluation Board
• Frequency translation, clock smoothing and jitter attenuation of the input
10MHz reference
• Datacom - DSLAM, DSLAR, Access Nodes
• Cable modem head end
• Base Station - GSM, CDMA
• Telecom - SONET/SDH/ATM
GENERAL DESCRIPTION
ABFT Evaluation Boards comprise of the Ultra Low Jitter ABFT Frequency Translator / Jitter Attenuator, which is ideally suited to improve the Jitter charac-
teristics 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

•
The ABFT Evaluation Boards are available with either the 20MHz or the 40MHz Translator
on-board
•
These boards provide a convenient means to conduct engineering evaluation of Abracon's
Frequency Tranlator / Jitter Attenuator Solution
•
The Evaluation Board is provided with standard SMA connectors for 10MHz Reference In, Supply
Voltage and Locked Output
•
The Evalautation Board can be tested over -40ºC to +85ºC Industrial Operating Temperature Range
- to quantify frequency tracking over temperature capability of Abracon's solution
