3 MEMS Oscillator 3 of 5 MECHANICAL DIMENSIONS AND PIN FUNCTIONING PIN SYMBOL FUNCTION 1 NC No connect. This pin will not respond to any input signal. It can be left floating 2 GND Electrical Ground 3 OUTPUT Output Signal 1 4 Vs Supply Voltage 2 Note: 1. Oscillator output signal. When interfacing to an MCU s XTAL, the CLK Out is typically connected to the Receiving IC s XIN pin. Oscillator includes an internal driver. The output swing and operation is not dependent on capacitive loading. 2. Connect to supply voltage 1.5V Vs 3.63V for operation over -40 C to +85 C temperature range. Under normal operation Conditions, Vs does not require external bypass/ decoupling capacitor(s). Internal power supply filtering will reject more than ±150mV p-p with frequency components through 10MHz.
