APPLICATIONS:
• Frequency translation, clock smoothing and jitter attenuation of the input
• 5x7x2 mm SMT, RoHS Compliant reflow-able package
• Frequency translation to either 20MHz or 40MHz carrier @ +3.3V Supply Voltage 10MHz reference
• Datacom - DSLAM, DSLAR, Access Nodes
• Industrial operating temperature range (-40ºC to +85ºC)
• 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.

Input signal must be
with-in ±20.00 ppm
from 10.00MHz
carrier for the ABFT
device to achieve lock
Referenced to the
stable input reference
of 10.00MHz (such as
a Stratum-III TCXO
or an OCXO)
This is the internal
pull range of the
ABFT device
providing sufficient
correction range to
account for internal
aging, stand-alone
temperature variation,
etc.

(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

Close to the carrier
phase noise is
dependent on the

However, at 1kHz
offset and beyond,
ABFT phase noise is
