Package Outline
s
SMD plastic encapsulated device.
Available over 0 to 70°C (IQXO-53, -57) or
–40 to 85°C (IQXO-53I, -57I)
Standard Frequency Stabilities
s
±50ppm, ±100ppm (inclusive of supply voltage
variations over the operating temperature range)
Operating Temperature Range
s
0 to 70°C (IQXO-53, -57)
s
–40 to 85°C (IQXO-53I, -57I)
Storage Temperature Range

Tri-state Control
s
Logic ‘1’ to pad 1 enables oscillator output, 2.0V min
s
Logic ‘0’ to pad 1 disables oscillator output; when
disabled the oscillator output goes to the high
impedance state, 0.8Vmax
s
No connection to pad 1 enables oscillator output
s
When oscillator is enabled, maximum transition time
= 100ns
