See solder profile page 2. PROCESS RECOMMENDATIONS Soldering Process Notes 1) Includes initial tolerance, deviation over temperature, supply and load variations, shock, vibration and 20 years aging. 2) When the oscillator is disabled, the outputs are at High Impedance. Output is enabled with no connection on pad 1. 3) Output must be terminated into 50 ohms to Vcc - 2V or Thevenin equivalent. 4) Duty Cycle measured at 50% of output swing.
