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)

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
