Frequency Translator / Jitter Attenuator RoHS ABFT Pb 5.00 x 7.00 x 2.0mm Compliant Moisture Sensitivity Level (MSL)This product is not Moisture Sensitive MSL = N/A: Not Applicable FEATURES: APPLICATIONS: Frequency translation, clock smoothing and jitter attenuation of the input 5x7x2 mm SMT, RoHS Compliant reflow-able package 10MHz reference Frequency translation to either 20MHz or 40MHz carrier +3.3V Supply Voltage Datacom - DSLAM, DSLAR, Access Nodes Industrial operating temperature range (-40C to +85C) Cable modem head end LVCMOS Output Base Station - GSM, CDMA Internal absolute pull range > 100 ppm allowing for long term drift correction Telecom - SONET/SDH/ATM 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.
