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

1ms 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

Output Levels

Output Voltage Levels:

Output High (VoH): Vs-0.4V min

Output Low (VoL): 0.4V max
