XOA53 Low Frequency Oscillator
5 x 3mm SMD oscillator with AT-Cut Crystal
32.768kHz
FEATURES
5 x 3.2mm SMD package with AT-Cut crystal for high stability
Frequency 32.768kHz for real time clock applications
Tristate (Enable/Disable) function as standard
Supply voltage 3.3V, 2.5V or 1.8 Volts
SUPPLY VOLTAGE DEPENDANT SPECIFICATION
DESCRIPTION
XOA53miniature oscillators consist of a TTL/CMOS-compatible hybrid
circuit together with a miniature AT-Cut quartz crystal packaged in a
low-profile, industry-standard ceramic package. The AT-Cut crystal
provides high frequency stability but with a low µA current
consumption, usually only available with a X-Cut crystal.

over Operating Temp. Range
Operating Temp. Range:
-10 to +70°C (Commercial)
-40 to +85°C (Industrial)
Supply V. vs. Freq. Stability: ±1ppm max.
Output Load: :
15pF
Duty Cycle:
50%±3% tyical, 50%±5% max.
Storage Temperature:
-55° to +125°C

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.
Enable/Disable Time:
Enable: 1ms max., Disab: 0.1µs max.
