Description
Frequency Divider Evaluation Board 60.4 x 42.7 x 13.0 mm ||||||||||||||| ABLNO-EVAL; Frequency Divider Evaluation Board shown in figure (1) is designed to facilitate engineering evalu- ation of Abracon’s Ultra Low Noise – ABLNO series of fixed clock and voltage controlled crystal oscillators. Further, there is a provision through the RF_IN SMA Connector to supply any other oscillator signal between 10MHz and 200MHz; if ABLNO series is not being characterized. This Evaluation Board is ideal to conduct the following measurements: • Phase Noise and rms jitter for ÷1, ÷2, ÷4 and ÷8 frequency outputs • Frequency Pull Characteristics of the ABLNO by using the Vc port as the control voltage • Frequency Stability over operating temperature (-40oC to +85oC) Figure (1) Designers who are interested in using the ABLNO as an Ultra Low Noise platform device to generate additional Low Noise frequencies will find this Evaluation Board to be of exceptional value. Abracon has implemented Ultra Low Noise ÷2, ÷4 and ÷8 circuitry on this board, that can also be incorportated in end-customer solutions; please contact tech-spport@abracon.com for additional details. Tpycial Phase Noise and jitter peformance in ÷1, ÷2, ÷4 and ÷8 modes is depicted in section 2.0.
