VCXO
16.384 MHz to 130 MHz
Miniature Surface Mount
Voltage-Controlled Crystal Oscillator
DESCRIPTION
5mm x 7mm
Statek’s 5 mm x 7 mm surface mount Voltage-Controlled
Crystal Oscillator is designed for applications requiring a highly-
pullable 3.3 V CMOS-output VCXO with a small footprint.
Offered at frequencies from 16.384 MHz to 130 MHz with
operation over wide temperature ranges (up to -40°C to
+105°C), these VCXOs offer exceptional performance in a
small package.

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.
