7 x 5mm SMD HCMOS
DESCRIPTION
XO91miniature oscillators consist of a TTL/CMOS-compatible hybrid
circuit together with a miniature quartz crystal packaged in a low-
profile, industry-standard ceramic package. The high quality design
and materials employed provide a highly reliable clock oscillator in a
miniature package while mass production methods ensure that the
XO91 provides a cost-effective oscillator solution.

Tristate Function (Pad 1):
Output (Pad 3) is active if Pad 1 is not connected or a
voltage to Pad 1 is 'HIGH'. Output is high impedance
when 'LOW' or GROUND is applied to Pad 1.
* Frequency stability is inclusive of calibration tolerance at 25°C,
frequency change due to shock & vibration, ±10 supply voltage
variation and stability over temperature range.
Note: Parameters are measured at ambient temperature of 25°C,
supply voltage as stated and a load of 15pF
