LVDS - LVPECL & CMOS Output

20 MHz to 300 MHz

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.
