Output Details

Output Compatibility LVPECL

Rise and Fall Time 0.5ns max

Duty Cycle 45/55% max

Output Voltage Levels:

Output Low (VoL): 1.680V max

Output High (VoH): 2.275V min

Output Control

Standby Operation:

Logic ‘1’ (70% Vs min) to pad 1 enables oscillator output.

Logic ‘0’ (30% Vs max) to pad 1 disables oscillator output.

No connection to pad 1 enables oscillator output due to

internal pull-up resistor.

Standby Current: 10μA max

Start-up Time: 10ms max

Noise Parameters
