IQXO-730, -731, 753, -757 SMD CLOCK OSCILLATORS
ISSUE 1; 24 MARCH 2010 - RoHS 2002/95/EC
Description
3.3V or 5.0V surface mount oscillators in a ‘J’ lead plastic
package, designed to withstand solder refow profiles up
to 250°C. These parts are offered as an alternative to
products which withstand solder reflow profiles up to 230°C
(see table below)

Tri-state (IQXO-731, -757)
Non tri-state (IQXO-730, -753)
Standard Frequency Stabilities
±50ppm, ±100ppm (inclusive of supply voltage variations
over the operating temperature range)
Operating Temperature Ranges
0 to 70°C (IQXO-730, -731, -753, -757)
–40 to 85°C (IQXO-730I, 731I, -753I, -757I)
Storage Temperature Range
–50 to 125°C
Tri-state Operation
Logic ‘1’ to pad 1 enables oscillator output,
Logic ‘0’ to pad 1 disables oscillator output; when disabled
the oscillator output goes to the high impedance state
No connection to pad 1 enables oscillator output
When oscillator is enabled, maximum transition time = 100ns
