OUTLINE & DIMENSIONS

DESCRIPTION

The DFXO series, 7 x 5mm SMD differential output oscillator is

designed for applications requiring low jitter and ultra high frequency

differential poutputs in a small footprint. Offered at frequencies from

20MHz to 300MHz with operation over a wide temperature range

(-40° to +105°C). No external decoupling capacitor is required with

optional internal capacitor.

There are two Enable/Disable options, T and N. THe 'T' version has a

Tri-state output and continues to oscillate internally when the output

is put into the High Z state. As a result, when re-enabled, the

oscillator does not have to restart and output with a stable frequency

resumes almost immediately. The 'N' version does not have PIN 2

connected internally and so has no enable/disable function. The

following table describes the Enable/Disable option 'T'.
