CXO OSCILLATOR
300 kHz to 170 MHz
Low Profile Miniature Surface Mount
Crystal Oscillator
™
DESCRIPTION
Statek’s surface-mount CXO oscillators consist of a Statek
miniature quartz crystal and a CMOS/TTL compatible hybrid
circuit in a low-profile ceramic package with a small footprint.
In addition to the conventional solder or epoxy electrical
connection techniques, bond pads on the topside of the CXO
allow it to be connected electrically in a hybrid assembly using
wire bonds.

ENABLE/DISABLE OPTIONS (E/T/N)
Statek offers three enable/disable options: E, T, and N.
Both the E-version and T-version have Tri-State outputs
and differ in whether the oscillator continues to run
internally when the output is put into the high Z state: it
stops in the E-version and continues to run in the
T-version. So, the E-version offers very low current
consumption when the oscillator is disabled and the
T-version offers very fast output recovery when the
oscillator is re-enabled. The N-version does not have
PIN 1 connected internally and so has no enable/disable
capability. The following table summarizes the three
options.
