描述 Description

Simple package crystal oscillator (SPXO) in a seam sealed

ceramic package with a metal lid and operates over a wide

supply voltage range of 1.62V to 3.63V

Wide operating temperature range (-40°C TO 125°C) for

industrial applications, not for Automotive.

Model IQXO-951 3225

Model Issue number 3

Frequency Parameters

Frequency 25.0MHz

Frequency Stability ±50.00ppm

Operating Temperature Range -40.00 to 105.00°C

±3°C and over the operating temperature range.

Electrical Parameters

Current Draw (no load) 12.000mA max

Supply Voltage: 1.62V min to 3.63V max

Output Details

Output Compatibility CMOS

Drive Capability 15pF max

Rise and Fall Time 6.0ns max

Duty Cycle 45/55% max

Output Control

Standby Operation:

Logic ‘1’ (>70% VS) to pad 1 enables oscillator output

Logic ‘0’ (<30% VS) 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.

Start-up Time: 10ms max

0.2ms typ to 90% of final amplitude (under ideal conditions @

25°C)

Standby Current:

1.5μA typ @ 25°C

10μA max over operating temp range -40 to 85°C

20μA max over operating temp range 85 to 125°C
