This product offers two different output logic control function options to facilitate the customer’s use of in-process assembly testing or for the use of multiple clocks. The EMS oscillator contains programmable power down (PD) and tri- state/output enable (TS) options for power management. If the power down function is selected, then all active circuitry within the oscillator is shut down when the voltage at the control pin (pad 1) is set to a logic low state. In this condition, the output signal is three-stated (tri- state) with a weak pull down (100k ohm typical) and the input current on the power supply line is negligible (standby current specification of 50µA). If the tri-state/output enable option is selected, the output is three-stated (tri-state) when the voltage at the control pin (pad 1) is set to a logic low state. In this condition, the oscillator and PLL continue to operate. However, the output signal is now high impedance) and the input current on the power supply line is
