Differential Output Crystal Oscillator
DESCRIPTION
5mm x 7mm
Statek’s 5 mm x 7 mm surface mount Differential Output
Crystal Oscillator is designed for applications requiring low jitter
and ultra high frequency differential outputs in a small footprint.
Offered at frequencies from 20 MHz to 300 MHz with operation
over a temperature range of (-40°C to +105°C). No external
decoupling capacitor required with internal capacitor.

ENABLE/DISABLE OPTIONS (T/N)
Statek offers 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 an output with a stable
frequency resumes almost immediately. The N-version does not
have PIN 2 connected internally and so has no enable/disable
capability. The following table describes the Enable/Disable option T.
