Frequency Translator-Evaluation Board Pb RoHS Compliant ABFT-20.000MHz-EVAL Moisture Sensitivity Level (MSL)–This product is not Moisture Sensitive MSL = N/A: Not Applicable FEATURES: APPLICATIONS: • 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 40 x 30 x 8mm | | | | | | | | | | | | | | • 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 - to quantify frequency tracking over temperature capability of Abracon's solution GENERAL DESCRIPTION ABFT Evaluation Boards comprise of the Ultra Low Jitter ABFT Frequency Translator / Jitter Attenuator, which is ideally suited to improve the 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.
